Now mix in a third green allele, which is dominant to blue, but recessive to brown..

Why do I have blue eyes but my parents don t?

The gene for blue eyes is recessive. Meaning that if someone has 1 blue and 1 brown gene, they have brown eyes; it’s called being heterozygote for that trait. Looks like your parents are both heterozygote, and you got the blue gene from both of them so you are homozygote for blue eyes.

Each child has a 25% chance of having brown eyes and a 75% chance of having blue eyes. This is simplified since the other eye color genes (like those that influence green eyes) are being ignored. But it does mean that brown (or green or hazel or…) eyes are a definite possibility for these blue eyed parents.

What nationality has hazel eyes?

The way light scatters in hazel irises is a result of Rayleigh scattering, the same optical phenomenon that causes the sky to appear blue. Anyone can be born with hazel eyes, but it’s most common in people of Brazilian, Middle Eastern, North African, or Spanish descent.

Can parents with brown eyes 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.

Which color eyes are dominant?

Eye color was traditionally described as a single gene trait, with brown eyes being dominant over blue eyes. Today, scientists have discovered that at least eight genes influence the final color of eyes. The genes control the amount of melanin inside specialized cells of the iris.

Why can two blue eyed parents have a brown eyed child?

Eye color is not an example of a simple genetic trait, and blue eyes are not determined by a recessive allele at one gene. Instead, eye color is determined by variation at several different genes and the interactions between them, and this makes it possible for two blue-eyed parents to have brown-eyed children.

Do purple eyes exist?
