For a simple trait with one dominant and one recessive gene, a person will only display the recessive trait if they are homozygous for the recessive trait. If they are heterozygous, they will have one dominant and one recessive gene, and the dominant gene will be expressed. If they inherit one copy of the recessive trait and one copy of the dominant trait, they will be a carrier of the recessive trait but will not display it themselves.
