Each person then has 4 total alleles that determine their eye color (in this simplified model). The B allele (brown) is always dominant over the G allele (green). The blue eye trait is always recessive.
What allele is green eyes?
Alleles are alternative forms of a gene that, in this case, are responsible for giving your baby a certain eye color. The allele genes come in the form of brown, blue, or green, with brown being dominant, followed by green, and blue being the least dominant or what is called recessive.
What traits make green eyes?
People with green eyes have a bit more melanin than people with blue eyes. The green color is from a combination of a blue hue from Rayleigh scattering and “yellow” from the yellow pigment called lipochrome. The higher the melanin concentration in the iris, the darker the eye color will be.

Can two brown-eyed parents have a green eyed child?
Two brown-eyed parents are likely to have a brown-eyed child. Again, it’s not guaranteed. Two green-eyed parents are likely to have a green-eyed child, although there are exceptions. Two hazel-eyed parents are likely to have a hazel-eyed child, although a different eye color could emerge.
Can 2 blue-eyed parents produce 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.
Why am I the only one in my family with green eyes?
Each chid inherits one copy of each gene from each parent, randomly, one in the sperm and one in the ova. So, a child could inherit the green gene from 1st parent, plus blue gene from 2nd parent. Green is dominant over blue, so they have green eyes.
