Detailed explanation-1: -The inheritance of eye color is more complex than originally suspected because multiple genes are involved. While a child’s eye color can often be predicted by the eye colors of his or her parents and other relatives, genetic variations sometimes produce unexpected results.

Detailed explanation-2: -Genetics and Eye Color You inherit one from the mother and one from the father. If the two alleles of a specific gene are different (heterozygous), the trait that is dominant is expressed (shown). The trait that is hidden is called recessive. Brown eye color is a dominant trait and blue eye color is a recessive trait.

Detailed explanation-3: -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.
