Differentiate between dominant and recessive traits

Dominant trait definition. In genetics, a trait that will appear in the offspring if one of the parents contributes it. (Compare recessive trait.) Note: In humans, dark hair is a dominant trait; if one parent contributes a gene for dark hair and the other contributes a gene for light hair, the child will have dark hair ... Recessive traits can be carried in a person's genes without appearing in that person. For example, a dark-haired person may have one gene for dark hair, which is a dominant trait, and one gene for light hair, which is recessive.
