Yes, if there is a history of blue eyes in the family (say, a grandparent, a great grandparent, an aunt or uncle, etc.). Since blue eyes aren't all that common, it takes two blue eye genes (one from each parent) to make a blue eyed baby.
Absolutely! I have a dear friend from childhood who looks like the odd man out in his family photo...His mom, dad and brother all have VERY dark brown eyes but he has the most brilliant blue eyes you've ever seen.
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.
If both the parents are purebreds for that trait then it will have a 100% chance of being brown. If the parent with brown eyes is a hybrid for that trait then the child will have a 50% chance of having blue eyes and 50% chance of having brown eyes.
yes i have green eyes, and my dad has blue, and my mom has hazel and my brother and sis have hazel
It indicates that the gene for brown eyes was not inherited by the child.
98.5% of the time they have the color of the parent that has the dominate color, not the resessive unless they both have a resessive color.
Yes, if both parents carry the recessive gene for blue pigmentation. If only one carries the gene, then there is almost no chance.
It is very very unlikely for this child to have brown eyes
The green eye and the blue eye are the same gene, so is black and brown. The child's eyes would have to be green or blue because both parents onlt have blue genes. If both parents have brown eyes there is still a chance the child's eyes could come out blue, but only if one of the parents have a hidden blue gene. But is both parents have blue eyes this means all their genes are blue and the child will 100% have blue eyes.
Yes, if the parents carry the gene for green eyes as a recessive gene.
no they cannot because if you have blue eyes, your alleles are bb, and so... bb and bb have no B, and therefore, with no dominant gene, there cannot be a brown eyed child.
Yes. Brown is dominant for eye color.
Not necessarily. A pair of blue-eyed parents may have a brown-eyed child. This is because there is more than one gene involved in eye-color determination. Please see the thorough explanation in the links.
That the trait for blue eyes was recessive in both parents.
Your wife had an affair; simple.
The gene for blue eyes is recessive.
The green eye and the blue eye are the same gene, so is black and brown. The child's eyes would have to be green or blue because both parents onlt have blue genes. If both parents have brown eyes there is still a chance the child's eyes could come out blue, but only if one of the parents have a hidden blue gene. But is both parents have blue eyes this means all their genes are blue and the child will 100% have blue eyes.
No... Brown eyes are an dominating gene. If none off the parents have brown eyes none of them have the brown eye gene to give the child.
Yes, if the parents carry the gene for green eyes as a recessive gene.
no they cannot because if you have blue eyes, your alleles are bb, and so... bb and bb have no B, and therefore, with no dominant gene, there cannot be a brown eyed child.
I don't think two brown eyed parents produce a blue eyed child, but a brown eyed parent and a blue eyed parent can produce a child with blue eyes. Brown eyes are not always dominate.Two brown-eyed parents CAN produce a blue-eyed child if BOTH carry the recessive gene for blue eyes. Recessive means it can hide, but is still present and ready to be carried on to a future generation. Brown eyes ARE dominant. If you carry the gene for brown eyes, your eyes are brown. This does not mean you can't also carry the recessive gene for blue/green eyes.
Blue eyes are a recessive trait, while brown eyes are dominant. If both parents are heterozygous for brown eyes, it means they both carry the recessive trait for blue eyes, and so there is a 25% chance their offspring will be blue-eyed.
98.5% of the time they have the color of the parent that has the dominate color, not the resessive unless they both have a resessive color.
Brown. What does the grandmother have?
Yes. Brown is dominant for eye color.
