Say like eye color any dark eye color is a dominant allele but green eyes are recessive for instance. My mom has blue eyes and my dad has brown, I would most likely have brown eyes because brown is more dominant over a light color like green.
What is the difference between dominant and recessive traits? Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive.
