Can a babys eye color and hair color be predicted?
No. The color of a person’s eyes is thought to be the result of the interaction of several different genes. The amount of pigment and its distribution in the eye determines whether a person has brown, hazel, green or blue eyes. The common belief that blue eye color, for example, behaves as “recessive” to brown eye color is not strictly true. There are many families in which both parents have blue eyes, but their children have brown eyes. The opposite can occur as well. Hair color is inherited in a similar manner to eye color, with many different genes involved. There is no genetic testing that can be done to predict or select the eye or hair color of children. The chance of having a child with a particular eye or hair color cannot be estimated by knowing the eye and hair color of the parents or other family members, as the genetic aspects of both traits in humans is poorly understood.
