What is the most recessive eye color?

The allele for brown eyes is the most dominant allele and is always dominant over the other two alleles and the allele for green eyes is always dominant over the allele for blue eyes, which is always recessive.

Can a blue eyed and brown 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. Eye color is not the simple decision between the brown (or green) and blue versions of a single gene. There are many genes involved and eye color ranges from brown to hazel to green to blue to…

Are blue eyes dominant over brown?

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.

Is Green dominant over blue eyes?

Blue will always be recessive. If both parents have a blue allele, it is likely that the child will have blue eyes. However, if one parent has green eyes and the other blue, your child will most likely have green eyes, as green is dominant over blue.

How do hazel eyes happen?

Hazel eyes are due to a combination of Rayleigh scattering and a moderate amount of melanin in the iris’ anterior border layer. Hazel eyes often appear to shift in color from a brown to a green. Although hazel mostly consists of brown and green, the dominant color in the eye can either be brown/gold or green.

Can I have blue eyes if my parents don t?

The laws of genetics state that eye color is inherited as follows: If both parents have blue eyes, the children will have blue eyes. The brown eye form of the eye color gene (or allele) is dominant, whereas the blue eye allele is recessive.

Is blue eye color dominant or recessive?

Two Pairs of Recessive Genes When both parents have blue eyes, as shown here, they will both have a pair of recessive genes for blue eye color. All of the children will therefore have blue eyes since there is no dominant gene present to mask the recessive gene.

What happens when both of the parents have blue eyes?

When both parents have blue eyes, as shown here, they will both have a pair of recessive genes for blue eye color. All of the children will therefore have blue eyes since there is no dominant gene present to mask the recessive gene.

Are blue eyes mutation or evolutionary?

When we started talking about mutations and evolution I quickly brought up the case of blue eyes. Blue eyes are a recessive trait and only appear when the mother and father are both blue eyed (or so I thought). Because it was recessive and required both parents to have blue eyes, I was sure that being blue eyed would die out.

What happens if you have 2 blue eye alleles?

If a person has 2 copies of the blue eye allele (both recessive) then the person would have blue eyes. Fig. 1 Illustration to show the inheritance of dominant and recessive alleles for eye colour.
