Who has the dominant eye color gene?

Question

The mother or father?

Mother - Brown Eyes (Her parents have blue & hazel eyes)
Father - Green Eyes (His parents & siblings have brown eyes)

Is there a genetic predisposition stronger a certain way?

I found this calculator, but what is funny is that when I enter my parents eye colors it tells me that it is an error because they could not product a brown eyed child. Maybe Mom never told me that I am the mailman's baby :)

Answer 1

Eye Color

If there were just one pair of genes involved in selecting eye color, there would be at maximum three shades of eye color -- brown, blue, and perhaps green. But human eyes come in a whole spectrum of different shades of these colors. That's because eye color is a polygenic trait.

Eye color is determined by the amount of melanin, or brown pigment, in the iris. Dark eyes have large amounts, blue have very little, and other colors -- green, hazel -- have varying amounts. Because different genes are probably responsible for how much brown pigment you inherit and where it shows up in the eye (more brown or blue can fall in the center or outer edges of the eye) there's a great possibility for a wide variety of hues. It's even possible for two blue-eyed parents to have brown-eyed offspring.

Answer 2

There is no dominance of one sex over the other.

That said, brown dominates, so if either parent passes on a brown gene, the baby will have brown eyes. However just because the parent has brown eyes, doesn't mean he's going to pass on that gene. If Mom gave the baby a blue gene, and Dad had one in there too (if he got green eyes, then he clearly has light eyes somewhere in there), the baby would have blue eyes.

If this is your family, I suspect your baby could have almost any color eyes, but brown would predominate. I don't remember the mathematical odds on this. Genetics was a course many years ago....

Answer 3

Brown is usually the dominant eye color. I have brown eyes, my husband has green eyes. My first son has brown eyes, my second son has blue eyes ( I don't know how I got lucky enough to get a blue eyed one) and my daughter has brown eyes. I was hoping my daughter would get green eyes like her daddy and then all 3 of my kids would have a diff. eye color. Now I was adopted so I don't know about eye colors on my side, but my husbands parents both have green eyes, and he was 1 of 4 boys, the first has hazel eyes and my husband and his 2 little bros all have green eyes. More than likely though your kids will get the brown eyes, I think there is only like a 25% chance of them getting a different color then brown. Good Luck!

Answer 4

Well there is more than one gene that influence eye color. Brown is dominant over blue or green. When the genes line up in the right way pigment mix and people get hazel eyes!

Answer 5

Genetics are pretty subjective and two blue-eyed parents can have a brown-eyed child. However, according to the simplest model, the child's predisposed to have either brown or green eyes. Both brown and green eyes are dominant, grey and blue eyes being recessive.

Answer 6

that is a good question. i know that all babies with the exception of african american and itallian kids babies are born with blue eyes. i have brown eyes and my ex had blue eyes and my daughter had hazel green eyes. it just all depends. i mean does it really matter.? it depends on the chromizones. and who wins the fight...lol.jk im not really sure..but i would say it would be in the grandparents genes..because all of my kids have most of my mothers features..

Answer 7

The father has the stronger genes, and the color brown is almost always dominate in most cases.

Answer 8

actually darker eyes are usually the dominant gene....usually. my husband has green/hazel eyes and i have dark brown eyes. our kids have darker brown eyes although my oldest son's(7) eyes are a slightly lighter brown
