what gene is dominant?

Question

I am 6 weeks pregnant and just curious about the eye color and hair color genes. My boyfriend has black hair and very blue eyes and I have light brown hair and dark brown eyes? What genes are dominant? thanks so much, i know the only way to be 100% is to wait to see but we are just curious =] thank you

Answer 1

Actually both of these traits do not rely on 1 gene. They rely on more then one for example

Eye color is 2 genes. Gene 1 carries a Brown and blue where brown is dominant over blue. Gene 2 carries a Green and Blue where green is dominant over Blue. ALSO the green in gene 2 is dominant over the blue in gene 1. there are also shades in between these and hazel eyes and eyes that change color and people that have 2 different eyes. I believe hair color works in a similar way. There are to many factors to consider.

Answer 2

Even though your boyfriend has black hair, he could carry the recessive gene for lighter hair. By the same token, even though you have brown eyes, you could carry a recessive gene for blue eyes. So almost any combination is possible for your child. And that's part of the wonder of it all.

Answer 3

brown eyes are dominant over blue eyes, however most babies are born with blue eyes and they change over time. your boyfriend(hopefully your soon-to-be husband) will give a blue eye gene(he has two because its recessive).. but you on the other hand could give brown, blue, or even green! i have green eyes - my mom has brown and my dad has blue, so its really unpredictable until the baby's eyes have matured. hair color on the other hand is even more unpredictable. your child is most likely going to have some form of brown hair, but once again there is a chance that both you and your boyfriend carry a gene for recessive blond hair.. thats the best i can do, but you'll have to wait and see! good luck!

Answer 4

Yes, brown eyes and brunette hair are the dominant genes

Answer 5

Definately dark hair and brown eyes. My husband is a blonde with blue eyes and I have dark brown hair and brown eyes. My son is 9m and has brown hair and his eyes...we don't know yet. They are still that bluish grey color with brown around the pupils. He has taken on my dark skin tone too.

Answer 6

...My husband and I have 2 children together.. I am blond/blue my husband is dark brown hair and brown eyes .... One of them has blue eyes and the other has brown eyes.. they both have very blond hair.. My first marriage, I have 2 children from and my X had black/green.. Both of the children have dark blond hair and blue eyes.... SO my guess would be your child will have blue eyes and brown hair.. Brown eyes are not as dominant as blue eyes... I was very lucky to have one of four children with brown eyes... Congratulations on baby!!!!!

Answer 7

usually the darker color is dominent but it is a possibility that the lighter one may come out if your husband has that particular gene, even if he doesnt have brown eyes it is likely that he has the gene for it.

Answer 8

Dark eyes and dark hair are dominant. Try this eye color predictor. I think it's really neat, it gives the chances of your baby having each eye color based on your genetics. http://museum.thetech.org/ugenetics/eyeCalc/eyecalculator.html

I don't know of one for hair though.

Answer 9

you ought to comprehend that merely a tiny fraction of alleles and genes artwork interior the elementary, classic way that Mendel defined. fairly than saying that allele A is dominant, it fairly is fairer to declare that, under maximum genetic backgrounds, allele A is fairly dominant over allele B. yet while allele C is likewise dominant over allele B, then something could desire to ensue in an organism with the two A and C. perhaps one among the two is fairly dominant over the different. perhaps it relies upon strongly on what alleles are cutting-edge in different genes. perhaps you get a co-dominant result. And comparable with 2 alleles which take place to be recessive while in comparison with another allele D. those 2 alleles could desire to be co-dominant to a minimum of one yet another, or you may desire to dominate the different, or maybe the end result's impossible to foretell, as a results of fact it fairly is in step with what's occurring in different genes, or our surroundings. It merely relies upon on the precise concern.

Answer 10

well which ever is the most dominant and I think the Blue eye color might be recessive.. lol I just learned this at school
