What are the differences in the set of alleles that produce skin color in a population of corn snakes called?

The differences in the set of alleles that produce skin color in a population of corn snakes are referred to as "color morphs." These morphs result from variations in genes that affect pigmentation, including the presence and distribution of melanin. The specific alleles associated with color traits can lead to a range of appearances, from bright orange to darker, mottled patterns. This genetic diversity contributes to the overall phenotypic variation within the population.
