science question-eye color ??

Question

ok what if you have brown eyes and dark hair , both of your parents have brown eyes and dark hair, but your dads eyes sometimes change to hazel and some of your dads family have blue eyes like his grandma and brother,and if you married someone with blue eyes,and alot of his family had blue eyes what would the chances be of your kids having blue eyes and dark hair ?
this is 4 science -sorry if this is unclear

I HAD 2 TYPE FAST NO RUDE ANSWERS !!!

Answer 1

Well about 50/50 I suppose but I don't know for sure. However I have hazel eyes and my dad has hazel eyes but his mom had blue eyes.Then I married a man with brown eyes but his mom and brother both have blue eyes. Now we have a daughter with blue eyes. Scientific explanation would be that the brown eyed gene is dominant over the blue eyed gene. If you get a blue eyed gene from one parent and a brown eyed gene from the other parent you will have brown eyes but you still carry a blue eyed gene in your DNA which you could pass on to your child. If you marry someone with blue eyes they only have blue eyed genes to pass on to their child. So the child will get only blue eyed genes from the father but can get either one from you and whatever eye color gene you pass on will determine the eye color of the child. Well I hope this helps you figure it out a little better. I know for a fact that a brown eyed couple could have blue eyed children as long as people in their family have blue eyes. However a blue eyed couple will never have brown eyed children . They will only have blue eyed kids. You can always call a pediatrician and they could tell you.

Answer 2

Eye colour is a complex inheritance with several genes involved and variable penetrance and expression involved so giving a precise answer is impossible. A simple answer, without percent chance, is that a brown eyed person and a hazel eyed person can have children with blue, green, hazel, light brown, brown or dark brown eyes. A brown eyed person and a blue eyed person can have children with blue, green, hazel, light brown or brown eyes.

Hair colour inheritance is also complex. Two brown haired parents could have a child with blond, red, brown or dark brown hair.

If the question is for a science test, check your textbook. It may be that the text book author provided a simplified explanation of the inheritance and a method for calculating percent chance. If so, your teacher will be looking for the answer that the textbook method calculates.

Answer 3

It's hard to get a kid with blue eyes and dark hair, actually. But it's not as recessive as people think. My Dad had black hair and blue eyes. My Mom had dark brown hair and green eyes. I got dark brown hair and blue eyes. I married a man with dark brown hair and brown eyes. I have 3 kids like him. The rest have green eyes, two of these were blond when young and then went dark. But my green-eyed daughter has a blue-eyed child. Her husband has blue eyes. So, at least I know blue can "fight back" against green......

Answer 4

Small possibility of child having blue eyes. The allele for blue eyes is recessive, meaning both parents must contribute a recessive allele that codes for blue eyes. If both of your parents have brown eyes along with yourself, it is less likely that you will be a carrier for this recessive gene. Since brown is dominant, this allele will always dominate over the recessive blue eye allele of your partner. It might give way to a lighter variation of brown or even hazel, but not blue.

Answer 5

Do not listen to Lovesol, they clearly have no clue what they are talking about. It is a recessive allel; however our genes are vast and can carry recessive information from a few generations back, they simply show the deminant gene. So it might be very rare, but you could get a blue eyed kid.

Answer 6

Its talked approximately as codominance. the place neither allele (gb on your case) is recessive or dominant so which you get a version between the two hues. Eye shade relatively hasnt been explored exterior of eco-friendly brown and blue.

Answer 7

I dont think it matters blue eyes is not dominant so your not gunna have it unless both parents have the gene

dont take my word from it i learned this last year kinda hazy
