What Color Will My Baby's Eyes Be? A Genetic Explanation

|

Genes come in pairs, and each gene in a pair may differ slightly. One gene may be dominant, and override the other gene, which is recessive. A recessive gene only has an effect if both genes in a pair are recessive. An example is eye color. Although this is not as simple as depicted here, blue is the recessive gene, and brown is the dominant gene.
