What causes green eyes to produce brown eyes in daughters?
The inheritance of eye color is determined by genes from both parents. If a person with green eyes carries genes for brown eyes, they can pass these on to their children. When both parents carry the gene for brown eyes, there is a chance that their child will have brown eyes, even if one parent has green eyes.
Can brown eye parents have green eye child?
It is possible, since the brown eyes could be a recessive or dominant trait in either the mother's or father's genotypes, and the father and mother might just be carriers of the brown eye gene in their genotype.
If you crossed a homozygous dominant man with brown eyes with a homozygous recessive woman with blue eyes what color or colors would their children have?
I don't know what your scientific terms mean, but I can tell you that I am a blue eyed female (my father was brown eyed/my mother had hazel eyes). The father of my two children is brown eyed. Both of my children have blue eyes.
Why do you have brown eyes when both your mother and father have blue eyes?
There had to be blue eyes within your genealogy. You need two recessive genes to produce blue eyes. Still, the bottom line is, it is very possible. There are individuals in my family that have blue eyes with parents that have brown eyes.
What color eyes will a baby born of one parent with brown eyes and one parent with green eyes?
Brown. Brown eye gene = B Blue eye gene = b Each person has two copies of the eye color gene in their genome, one inherited from each parent. Now if both parents only carry the gene for brown eyes, BB and BB, then their child will receive one B from each parent, ending up as BB. The same works for blue eyes, if that's the only gene both parents carry, bb and bb. Each parents gives on b to the child, who ends up as bb. If you have one parent who only has the gene for brown eyes, BB, and one parent who only has the gene for blue eyes, bb, then all the children will have brown eyes. Example: One parent gives a B, the other gives a b. Bb = brown eyes. Here's why: When you have two alleles (coding sequences) from genes that are at odds with each other, one version will override the the other. When dealing with eye color, B always dominates b. But these children now carry the b gene in them, and could pass it down to their own children. Some of them, depending on the other parent, could end up with blue eyes. If one parent is Bb, and the other is bb, then each time they have a child, there is a 50% chance it will have blue eyes. Example: First parent is Bb, second parent is bb, then their children will end up as either Bb, bb, Bb, bb. If both parents carry the genes for brown eyes and blue eyes, then each time they have a child, there is a 25% chance it will have blue eyes. Example: First parent is Bb, second parent is Bb, then their children will end up as either BB, Bb, Bb, bb.
Are blue eyes more dominant than brown eyes?
No, brown eyes are more dominant than blue eyes genetically. Brown eye color is a dominant trait, while blue eye color is a recessive trait. This means that if a person has one gene for blue eyes and one gene for brown eyes, the brown eye gene will be expressed.
What color would your eyes be if your parents have different eye color?
if your parents have different color eyes: if eyes are not brown, no brown gene lets say one green other brown. green parent may have green/blue gene. brown parent may have brown/green gene. your eyes might be blue. 1/4 chance of it.
Can to brown eye mom and dad have a kid with blue eyes?
Yes. If the mom and dad both have one recessive gene for blue eyes, there is a 25% chance that the child will have blue eyes. Since the blue eyed gene is hidden when the brown eyed gene is present, the parents will appear to have brown eyes even if they still contain the gene.
An expressed gene is one that what?
a gene being expressed means it is shown, for example if you have the gene for brown eyes and the gene for blue eyes, only one can be expressed. if you have brown eyes that gene is expressed, if not the blue-eye gene is expressed.
If father and mother both have blue eyes is it possible to have a baby with brown eyes?
There is a chance the baby will have blue eyes but only 1:3 chance. You carry 2 blue eye genes. If he carry's 2 brown genes then all your baby's will have brown eyes. But, if he carry's 1 brown gene and 1 blue gene then the chances of blue:brown eyes are 1:3. Hope this helps :)
What causes green eyes to produce brown eyes in daughters?
The inheritance of eye color is determined by genes from both parents. If a person with green eyes carries genes for brown eyes, they can pass these on to their children. When both parents carry the gene for brown eyes, there is a chance that their child will have brown eyes, even if one parent has green eyes.
If blue eyes are caused by a recessive gene why then are there any children with blue eyes anymore Shouldn't all children now have brown eyes Explain why this isn't the case?
Blue eyes being recessive just means that someone must have 2 blue-eye genes to have blue eyes. If they had one brown-eye gene and one blue-eye gene, they would have brown eyes but their kid(s) might have blue eyes, depending on the genetics of the other parent.
What color will a baby's eyes be if the mom and dad both have brown eyes?
Most likely brown, brown is a dominate gene. So probably brown eyes - but you never know :) brown eye color is a dominant trait, so most likely brown but it is a polygenic trait, which means more than one gene is responsible for determining eye color.
What eye color would your child have if one parent had blue eyes and one had brown eyes?
Your boyfriends brown eyes will be dominant, though there is a chance that your child could have blue eyes. I'm not sure if there's an exact percentage, but it wont be high. Brown is very dominant. Especially because of the fact that both his parents have brown eyes as well.
1 albino baby gerbil born to a brown mother there are brown and white fur males who might be the father?
There is no such thing as an albino gerbil. There are red-eyed white gerbils, but they are not albino as they have one gene that causes red eyes and another that causes white fur, instead of a single gene causing albinism. Now, depending on the recessives of the brown father, it could be either. The mother is obviously carrying a c(h) gene.
You have dark brown eyes and your husband has light brown eyes what color will your babies eyes be?
It depends if your eye color is BB (brown/brown). This means that you have two copies of the brown eye color gene or if you have one recessive blue gene (Bb). Your husband has blue and he has bb or two genes for blue. If you have BB, all your children will have brown eyes. All the children will also have a gene for blue (Bb). If one of your parents has blue eyes, you can carry a recessive gene for blue. If you are Bb, the children will have 50:50 chance of having either Brown or blue eyes.
Can brown eye parents have green eye child?
It is possible, since the brown eyes could be a recessive or dominant trait in either the mother's or father's genotypes, and the father and mother might just be carriers of the brown eye gene in their genotype.
