Baby Eye Color Predictor Calculator

Generally, children inherit their eye color from their parents. Our Baby Eye Color Predictor Calculator predicts your baby's eye color by selecting the mother's and father's eye colors. But inheritance of eye color is not that simple because it is polygenic. Polygenic means that the trait is influenced not by one gene, but by different genes working together.

Each person carries two copies of every gene, one copy inherited from the mother and the other inherited from the father. Homozygous means that the two copies match. For example, maybe both copies are for brown eyes. A heterozygous person has two non-identical copies of the gene. For instance, one brown and one which is not brown. Hence, it is beyond the bounds of possibility to ascertain if a person is homo- or heterozygous by just seeing the person's eyes.

When genes mutate, they form alternative forms which are called as alleles. If the child receives a recessive allele (blue) from one parent and a dominant allele (brown) from the other then the child will have brown eyes. If the child receives recessive blue alleles from both the parents and no dominant allele from either of the two, the child will have blue eyes. If the child receives green alleles from both the parents or one green allele and one blue allele then the child will have green eyes. However, a child’s true eye color cannot be fully determined until the age of 3.
