Blue eyes + blue eyes = 100% chance of blue eyes. Brown eyes + blue eyes = 50% chance of blue eyes, but only if the brown-eyed parent carries a blue-eyed gene. If not, the chance is 0% Brown eyes + brown eyes = 25%, but only if both parents carry the blue-eyed gene.
Which parent determines eye color?
The chromosomes a child inherits carry genetic information that determines eye color. Differences in the copies received from each parent causes variations in the amount of melanin produced. A region on chromosome 15 has a big part in determining eye color. The OCA2 and HERC2 genes are located in this region.
Are blue eyes dominant or recessive?
The brown eye form of the eye color gene (or allele) is dominant, whereas the blue eye allele is recessive. If both parents have brown eyes yet carry the allele for blue eyes, a quarter of the children will have blue eyes, and three quarters will have brown eyes.
Are blue eyes the rarest eye color?

Who has stronger genes mother or father?
Genetically, you actually carry more of your mother’s genes than your father’s. That’s because of little organelles that live within your cells, the mitochondria, which you only receive from your mother.
Can a brown eyed male and a blue eyed female have a blue eyed child?
The only way to present blue eyes is to inherit two copies of the blue-eyed gene. However, brown-eyed parents can pass a recessive blue-eyed gene. Therefore, two brown-eyed partners can birth a blue-eyed baby. … Brown eyes + blue eyes = 50% chance of blue eyes, but only if the brown-eyed parent carries a blue-eyed gene.
Can blue eyed parents have a green eyed child?
First, the answer is yes to both questions: two blue-eyed parents can produce green or brown-eyed children. … However, because many genes are required to make each of the yellow and black pigments, there is a way called genetic compensation to get brown or green eyes from blue-eyed parents.
What do blue eyes mean genetically?
People with blue eyes have a single, common ancestor, according to new research. A team of scientists has tracked down a genetic mutation that leads to blue eyes. … The mutation affected the so-called OCA2 gene, which is involved in the production of melanin, the pigment that gives color to our hair, eyes and skin.
Can two blue eyed parents have a hazel eyed child?
Yes, blue-eyed parents can definitely have a child with brown eyes. Or green or hazel eyes for that matter. … This has to do with the fact that blue eyes are supposed to be recessive to brown eyes. This means that if a parent has a brown eye gene, they’ll have brown eyes.
