How genes determine 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.
Which parent carries the gene for eye color? What determines a baby’s eye color? In general, children inherit their eye color from their parents, a combination of the eye colors of Mom and Dad. A baby’s eye color is determined by the parents’ eye color and whether the parents’ genes are dominant genes or recessive genes.
Which eye color gene is more dominant? 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.
Is eye color determined by one gene? 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.

Precise Color Communication. The human eye cannot differentiate some colors from others even if they are different. The area of such colors on the chromaticity diagram is called the color discrimination threshold of the human eye.
Is eye color inherited?
Whether eyes are blue or brown, eye color is determined by genetic traits handed down to children from their parents. A parent’s genetic makeup determines the amount of pigment, or melanin, in the iris of the his or her child’s eye. With high levels of brown melanin, the eyes look brown.

What decides eye color?
Eye color is determined by variations in a person’s genes. Most of the genes associated with eye color are involved in the production, transport, or storage of a pigment called melanin. Eye color is directly related to the amount and quality of melanin in the front layers of the iris.
