I know the gene is dominant but is it always?
(i.e..) You have a cleft chin but DH doesn't...and you have 3 kids (different times of course) Will all 3 of them have a cleft chin?
Every since the one episode of HOUSE where the one boy knew he was adopted because his "Dad" had a cleft chin and he didn't....I have been looking at parents who have it and then their kids to see if they have it as well ahaha
there is always a chance for the dominant gene to become recessive. like my mom and dad have brown hair and brown eyes and so do i but my sister has blue eyes and blonde hair.
Neither one of my parents have it but my sister does. She got it from my mom's dad. So if he had it and my mom doesn't, I think that answers your question lol
Isn't darker hair and eyes dominant?
If so then I got the non dominant gene. I have red hair and blue eyes.
I mean you dont ALWAYS get the dominant feature.
I'm not so sure it always is.
My brother and sister have the same parents, but she has a butt chin and he doesn't.
Neither of their parents have one.
I was taught that dominant traits mix like such
CC and Cc= cleft chin (dominant trait) CC Cc
cc= recessive chin trait Cc cc
So each child has a 25% chance of not having a Cleft chin.
This is gonna sound strange, but that doesn't mean if you have 4 kids only one has a chance of not having a cleft chin.
It's easiest to figure out with the Punnett Square.
