Question 15

In corn snakes (Elaphe guttata), the allele for wild-type coloration (EEE) is dominant to the allele for amelanism (eee), which results in a lack of black pigment.

Explain how two parent snakes, both displaying the wild-type phenotype, can produce offspring with the amelanistic phenotype.
