    You are working with an ornamental fish that shows two color phenotypes, red or blue. The color is controlled by a single gene. These fish are hermaphrodites-meaning they can either (1) self-fertilize or (2) mate with another fish. You have three fish: fish 1, fish 2, and fish 3. While working further with this fish, you discover one other mutation (in a different gene) that leads to the recessive phenotype of long dorsal fins. Further research establishes that the genes...
