Question 1

In a certain species of fly, eye color is designated by the W+ and w alleles, with the W+ allele being dominant. Typical eye color is red for these flies, while a rarer white color variant exists. There is also a pink eye color that occurs when flies inherit both the W+ and w alleles. The pink phenotype is an example of ________.
