Can a child have blue eyes if both parents have brown eyes?

Answer 1

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.

Answer 2

Yes, it is possible for a child to have blue eyes if both parents carry the recessive gene for blue eyes. Blue eyes are a recessive trait, so both parents must have at least one copy of the blue eye gene for it to manifest in their child.

Answer 3

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.

Answer 4

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.

Answer 5

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.

Answer 6

yes i have green eyes, and my dad has blue, and my mom has hazel and my brother and sis have hazel

Answer 7

It indicates that the gene for brown eyes was not inherited by the child.

Answer 8

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.

Answer 9

Yes, if both parents carry the recessive gene for blue pigmentation. If only one carries the gene, then there is almost no chance.

Answer 10

It is very very unlikely for this child to have brown eyes
