Case: The colors of the fruits that a pepper plant produces are controlled by two different genes. The gene aureus is required for the conversion of green pigment to yellow pigment. The alleles for aureus are "a+" (wildtype) and "a-" (an amorph). The gene ruber encodes for a protein that converts the yellow pigment to a red pigment. The alleles for ruber are "r+" (wildtype) and "r-" (a hypomorph). Aureus and ruber are on the same autosome and are 10cM apart.
