If pregnancy wasn’t overwhelming enough with all the pains, aches and the complete inability to get comfortable, it is also a slow ordeal. It is a long wait to find out your baby’s gender and an even longer wait to meet them and see what they look like. It is a wait that a lot of parents just can’t handle.
Science has come a long way when it comes to helping mom and dad get a sneak peak at what their little bean looks like with the help of 3D ultrasounds. With this technology, we may get a pretty good idea of facial shape, but what about the details? Eye colour, hair colour and other little features that we are all waiting to see.
We know that babies get their genes from their parents, that is how they are made. What we may not know is how these exactly work. How do these genes mix and create a perfect and beautiful little person? Where do the cute cheeks come from or the big pout? Do they come from anyone or is it just a fluke? If we look at science and the specific way that genetics work, we may be able to get a good idea of what the little ones will look like!
We dived in deeper and we are pretty sure we have found sound excellent ways that mom and dad can look in the mirror and guess at what their baby will look like. We will start by looking at how genes work, a brief explanation, and then break it down feature by feature to try and bring every expectant parent a clear image of the adorable baby they have coming their way.
15 Brief Look At How Genes Work
Genetics may seem like an overwhelming thing to understand unless you are a scientist. I am not, and words like DNA and genetics tend to make me sweat a little bit as I am taken all the way back to high school biology class, and no one wants to relive that. We are going to try and break it down to the most basic of explanations so that we all have a better understanding of how our baby comes to be our baby.
Every human being has 46 chromosomes, and experts claim that there are an estimated 60, 000 to 100, 000 genes in all of them. See, complicated!
A baby is also made up of 46 chromosomes, he gets 23 from his mother and 23 from his father, and equal share. There are so many genetic combinations that could be made that it is possible for a woman and man to produce 64 trillion different looking children.
With that being said, it is difficult to nail down exactly what your baby will look like. We can, however, look at dominant genes that will give you the highest likelihood of the traits your little one will have.
14 Baby Blues?
Let’s start with the one trait that people want to know about the most: eye colour. Parents want to know if their baby will have those bright, clear blue eyes or the stunning shade of brown. While it is impossible to predict for sure, if we look at the eye colours that the parents have, we may be able to make an educated guess on the colour of the baby’s eyes.
The old tale went that brown eyes were always dominant, and that two brown eyed people could never make a blue-eyed baby. That is not true.
Eye colour is determined by many genes, and it is not so simple as just the two colours. Eye colour is determined by the amount of brown pigment in the iris. If the eye has more brown pigment, the eyes will be brown. Blue eyes mean that the eye has very little brown pigment. If the eyes are green, hazel or grey that means that there are varying amounts of the pigment. With that being said, it is more likely that two parents with brown eyes will produce a brown eyed baby due to the prevalence of brown pigment gene that is passed down.
13 Dimple Or No Dimple?
Have you noticed those little babies who have those dimples on their cheeks? What a silly question, of course you have because they are just too adorable. If you are expecting you may want to know the likelihood that your little one will have dimples as well. We all just want to have the cutest baby in the whole world. There are a couple pieces of good news here; the first is that dimples or not, your baby will be adorable. The second is if one parent has dimples, chances are your baby will sport them as well.
Dimples, along with other facial features like widow’s peak and facial symmetry, are all heavily believed to be dominant genes. They even may filter down through generations, so if a grandfather or grandmother had dimples but the parents don’t, that gene could also be passed down.
It is amazing how genetics work and sometimes it just seems like it is luck of the draw which genes your baby will have. Even something like freckles are considered a dominant, or stronger, gene. If mom or dad has freckles, chances are that your baby will have freckles. Freckles take a while to develop on the skin, so don’t fret if your baby is born without freckles, there is still time.
12 Oral Structure Is Already Determined
We don’t always think about our teeth, we take them for granted. We just know they are there and they help us chew food, but we don’t really think about where they come from. Teeth come in all forms of shapes and sizes, and some people have perfectly white and well-shaped teeth while others have a more crooked look to their smile.
Want to know what kind of teeth and mouth your little one will have? Look no further than in the mirror because teeth are another thing that is determined by genetics.
It may take a long while before you get a good look at the kind of mouth your baby has, because you must wait until their adult teeth have all come in. The reason we can look at mom or dad and determine what the baby’s teeth will be liked is because the configuration of the jaw and the tilt of the teeth are genetically determined. They have even located a specific gene that is responsible for “gap tooth” and it has been told that this is a dominant gene. So, if mom and/or dad needed braces, then you better start saving now because chances are your little one will as well.
11 Old Wives' Tale For Height?
When we are expecting we don’t often think about how tall our child will be. We just think of them as the small, plump, cute little babies. These babies will grow up to be an adult, and it may be amazing for you to know that they are stating that height is genetic and there is a way to determine how tall your child will grow to be.
For a rough estimation of how tall your child will grow up to be, take the average of mom and dad’s height. Then add two inches for a boy or subtract two inches for a girl.
Confused? Let me give you a scenario. If mom is 5 feet 2 inches and dad is 5 feet 10 inches, the average height between you would be 5 feet 6 inches. If you have a son, you would add 2 inches meaning your boy will be 5 feet 8 inches, and if you have a girl you would subtract 2. This means your little girl will be 5 feet 4 inches. Of course, this is just an approximate and it is not an exact science. You will also need to wait a little while before putting this to the test to see if this was true. If you are reading this and have adult children, do the math and see if it is accurate!
10 Long, Beautiful Hair … Or None?
They say that if mom has a lot of heartburn when she is pregnant that her baby will be born with a full head of hair. As fun as old wives’ tales are, they are not really scientifically reliable. There is a science to the kind of hair your baby will have, and we need to look no further than genetics. Sorry to disappoint any mom out there who has a lot of heartburn and is thinking they are getting a baby will a full head of hair, it doesn’t quite work that way.
If we look at things generally, dark hair is more dominant. If both parents have darker shaded hair, than chances are your baby will have darker hair as well.
Hair colour works similar to eye colour though, so even two dark haired parents can have children with various shades of colour. What this also means is that parents can get one heck of a surprise when it comes to hair colour.
It is possible for two brunettes to end up with a red-haired baby. It may be rare, but it does happen. All genes can skip a generation and even recessive genes can show up every once in a while.
9 Cleft Chin
Do you know what a cleft chin is? All I need to tell you is to look at John Travolta, he has a very defined cleft chin. Basically, it means that there is a small dimple in the middle of a person’s chin.
If you or your partner has this, what are the odds that your baby will have one as well? A cleft chin is an inherited trait and it is a dominant gene. So, if mom or dad is sporting this chin dimple, chances are their baby will have one as well.
Medically, a cleft chin is a Y-shaped fissure on the chin. The chin follows the fissure in the lower jaw bone that resulted from an incomplete fusion of the left and right halves of the jaw bone, or muscle, during development. This is not something to medically worry about, it doesn’t cause the body any harm. An interesting fact about a cleft chin is that if we look in Persian literature, we will learn something interesting. The chin dimple is considered a factor of beautify and is often referred to as “the chin pit” or “the chin well.” This I where a poor lover is fallen and trapped. Learn something new every day.
8 Pouty Lips
It is amazing how little we pay attention to facial features until we are pregnant. Once we see those 2 pink lines all we can think about is the shape of our partners nose or that weird mole. We over analyze anything and everything that could be passed on to our baby. We will even start to pay attention to lips and wonder the likelihood of lips being passed on. Well, the answer is highly likely. Genetics play a part in everything, right down to the shape of the lips.
It turns out that pouty, full lips are the dominant gene. So, if mom or dad has a big pouty smile than chances are that baby will come out with luscious looking lips.
That’s right, they may be born with a trait that a lot of people pay a lot of money to achieve. Even if you go back to your parents or grandparents and find a set of pouty lips there is a chance that your baby will have got that gene. Genetics are very interesting, and it is almost overwhelming to realize that everything we are is because of certain genes that were passed down.
7 What They Will Look Like On The Inside
We have talked a lot about physical features, and a lot of parents do immediately want to know what their baby looks like. There comes a time when parents may start to wonder who their child will be. Once the baby is born, they wonder what their personality will be like and are very excited to see it start to develop and blossom. It got us all thinking, do our genetics play a part in who we become as a person?
Scientists are mixed on this one. They say that there is no doubt that some personality tendencies are hardwired into us from birth, such as how we react to noises. Experts also believe that a lot of our personality is also dictated by our environments.
They have detected a gene that predisposes children to more risky behaviours. So, if you both are very adventurous, you may be lucky enough to have a child who has a no-fear attitude. The same goes for children who are born to creative parents. Parents who have a talent in music or art may birth a child that carries on with that gene. The good news is that even if the child is not born with any gene, they are human, and with hard work they can achieve anything they want too.
6 More Likely To Be A Certain Size
Obesity is a problem in the US and all over the world, and society has come a long way in realizing that it’s not always just about diet and exercise. A lot of the time these are medical concerns that need to be treated. It is worrisome to larger parents that they may be setting up their child for failure already just by giving birth to them. How much is weight predicted by genes?
Turns out, it is very likely that if you and your partner are an unhealthy size, chances are your child will be as well.
Now, not all hope is lost. There are certain environmental changes that mom and dad can make to try and reduce this risk or the severity of it. Starting the baby off on healthy foods and making sure they have all the outside time that they can take are just two ways to help. They are currently doing more studies on an “obesity gene” and experts are looking into this a lot more. Of course, there are certain medical conditions that can cause a person to put on weight, these concerns should be discussed with your doctor about what the right course of action is for your child.
5 Fingerprints Are Part Of The Package
We are all unique in some way, but perhaps the most unique feature on us are our fingerprints. No two are alike, so there is no way this could be traced to genetics, right? Wrong! It turns out that even genetics play a part in our fingerprints.
Fingerprint patterns have been linked to genetics, so while no two sets of fingerprints are alike, the patterns are similar.
Let’s take a moment to talk about twins and how their genetics work. Identical twins are made of a single egg that split in utero. This means that they have the exact same DNA, even down to their fingerprints. If a set of identical twins did one of those ancestry DNA tests that seem to be all the rage right now, their results should be 100% identical. Fraternal twins are from two separate eggs, so while they share a womb, they are genetically completely different. The fraternal twin gene is hereditary, but not the identical twin gene. Fraternal twins come from a woman releasing multiple eggs, so it is not uncommon for twins to have twins. Experts can not say if this is a dominant gene, because they can not be sure how many fraternal twins there actually are, as sometimes one twin passes away before the mother even knows.
4 A Chance Of Any Mutations?
Now, not all genes are created equal, and they are definitely not all good. There are some genes that we do not want passed on to our children. Illnesses, diseases and even malformations that we know run in our family and we are terrified that through no fault of their own that they may be born with one of these concerns. What exactly are the chances of this? Are we all worrying for no reason? The truth is, genetics is similar to a game of chance, or a lottery. Most of the time, we can never predict exactly if conditions will be carried on.
Mutations come from the parents mix of DNA, there is a chance that they will split and put themselves back together in the wrong order. This will not happen unless it is influenced by the mother or father.
If mom has a mutation, there is a chance that the mutation will either carry on or will correct itself through her child.
Most mutations that are life altering can be detected through prenatal screening, others are minor and are not something to be concerned about. If you are concerned about possible mutations, speak to your healthcare provider who can provide you with more information.
3 What Will That Brain Look Like?
We’ve talked about physical features, and we have even talked about personality, but can we predict a baby’s intelligence by looking at genetics? Are two intelligent people more prone to have a baby that is advanced and brilliant? Again, the answer is yes, because genetics make up every single fiber of our being. If two intelligent people, with high IQ, have a baby, chances are pretty high that the baby will be intelligent as well. Don’t expect the baby to come out talking though, it doesn’t quite work that way.
If the baby has one parent who is intelligent, and the other parent has different skills, there is no way of knowing how the baby will be. Smarts have not been linked to a specific gene.
The environment also plays a factor in the intelligence of a child, how they are raised and the opportunities they are given may play a large part in their successes. The experts are working to figure out if there is a “genius gene” and just how dominant it would be. It also could be recessive, meaning two IQ geniuses may end up with a child who is, well, we will just say different than his mom and dad.
2 Lost Of Smiles? Or Frown City?
There is nothing better than a smiling baby. Sure, those first few little smirks are more than likely gas, but that day will come when your little one looks up at you and flashes you that perfect little smile. Did you know that genetics can tell you if your baby is more predisposed to be a smiler?
There currently is no discovered “funny gene” but it has been noted that babies who are born to happier and funnier parents tend to have the same temperament.
Babies react to their surroundings, and if they are always around parents who are happy and smiling, they will act the same way. This one may be based on environment and have little to do with genetics, but since we already know that genetics play a factor in a baby’s personality, then we can only assume that part of that would include their sense of humour and willingness to smile. So, it is time to bust out the good old ‘dad jokes’ and practice them on your baby, they may just get you that smiling, sweet little baby you have always wanted. Is your baby always frowning? Maybe take a look in the mirror and observe how you look and maybe just smile a little more.
1 Let’s Talk About Earlobes!
Have you ever really looked at yours and your partners earlobes? Probably not, it is not generally something we pay attention to when we talk to other people. Know that I have pointed it out, I am sure you are studying all the earlobes around you. You may have noticed that earlobes come in two very specific shapes. One is a detached earlobe, one that has the noticeable drop. The other is earlobes that are attached to the side of the person’s face. Is this genetic? Yup.
A baby gets an earlobe gene from their mother and from their father. In the case of when it comes to earlobes, the dominant gene is those of the detached earlobe.
The one where the bottom of the ear seems to hang down instead of attached right to the side of the face. This means that by looking at you and your partner you can determine what kind of ears your baby may have. If both parents have detached ear lobes, chances are their baby will as well. If mom and dad have one each, then chances are that baby will get the detached earlobe gene.
