My father' has blue eyes and my mother has hazel eyes, I have brown eyes. Where do my brown eyes come from?

Question

I have read about Mendel's laws about inheritance and eye colour but my eye colour does not match the inherited eye colour principles. Is there a physiological reason why my eye colour is different to my parents or is there some other reason? I would welcome any feedback.

Answer 1

They could come from someone else in you family...your aunt,uncle,grandma,grandpa,great grandparents...ect..hope this helps!

Answer 2

Could be a grandparent or even a more distant relative.  My mom had brown eyes and my dad and brown eyes and I got hazel eyes, which is a variation of brown, so maybe with your mothers hazel eyes, you got brown, the opposite of what I got.  No worries, my eyes are hazel and my husbands blue, my son has green eyes and my daughter has blue so eye color doesn't always have to follow one parent or the other.

Answer 3

Eye colour is determined by at least three genes which can each have some variability in expression.  So the simple Mendelian charts won't help.

A blue eyed and hazel eye parent can have children with grey, blue, green, hazel or brown eyes.

Answer 4

Maybe your father is your "step-father", if you know what I mean.

Answer 5

You can actually look to your grandparents or even their parents and find where the trait comes from.  It does not necessarily have to come from your immediate parents.  (I had to do an experiment on fruit flies that show recessive and dominant traits and the probabilities)  Brown eyes are a dominant trait.  Your parents could still carry that trait even if their eyes are not that color.  Which, will then pass on to you especially if they both carry a brown eyes trait in their gene's from other family members.  

Answer 6

Maybe your "real" father has brown eyes. Ha ha. Just kidding. I don't know, but genetics are a weird thing, it could be from a grandparent or further up the family tree.

Answer 7

Dude, this is a loaded question to ask on Yahoo Answers. But If you welcome "any feedback" here is one dumb opinion. Maybe cause your full of s___T?

Answer 8

maybe a grandparent of urs

Answer 9

I'm not genius on Mendel's laws, but I have heard of them.  So, don't go on what I say, but I do have a guess.

Your dad has blue eyes.  In order to have blue eyes, you must have two "blue eye" genes because blue eyes are always recessive.

Your mom has hazel eyes.  I'm not sure, but she probably has one "brown eye" gene and one "blue eye" gene.  Brown eyes are always dominant.  Her blue gene brings out the "hazel" in her brown gene.  I know that sounds stupid, but I don't know how to say it.

You have brown eyes because probably, your mom gave you her brown eye gene and your dad gave you the only gene he has, the blue one.  Brown eyes are dominant, so the brown gene overpowers the blue one from your dad.

Answer 10

Eye color is determined by the amount of brown pigment in the iris. Blue eyes are the result of virtually no brown pigment and hazel eye color is a moderate amount of brown pigment. So it is possible that you can have brown eyes because you just have more brown pigment than your mother or father.
