Detailed explanation-1: -Siblings can inherit various genes from their parents and they don’t always get the same ones. Depending on what genes they get and the way that these genes are turned on or off and expressed, can play a role in eye color.
Detailed explanation-2: -Yes. The short answer is that brown-eyed parents can have kids with brown, blue or virtually any other color eyes. Eye color is very complicated and involves many genes.
Detailed explanation-3: -If both parents have blue eyes, the children will have blue eyes. If both parents have brown eyes, a quarter of the children will have blue eyes, and three quarters will have brown eyes. The brown eye form of the eye color gene (or allele) is dominant, whereas the blue eye allele is recessive.
Detailed explanation-4: -All Blue-Eyed People May Have A Common Ancestor Originally we all had brown eyes, however, according to researchers at the University of Copenhagen, it appears that a genetic mutation in a single individual in Europe 6, 000 to 10, 000 years ago led to the development of blue eyes.
