6. The white eye mutation studied by Thomas Hunt Morgan is X-linked and recessive to wild-type red eyes. When true-breeding white-eyed males carrying the white mutation were crossed with true-breeding purple-eyed females, all the F1 progeny had wild-type (red) eyes. When the F1 progeny were intercrossed, the F2 progeny emerged in the following ratio: 3/8 wild-type females 1/4 white-eyed males 3/16 wild-type males 1/8 purple-eyed females 1/16 purple-eyed males. Formulate a hypothesis to explain the inheritance of these eye colors and match the correct genotype with each individual listed below. 1. P Generation Male 2. P Generation Female 3. F1 Generation Male 4. F1 Generation Female 5. F2 Generation Purple-eyed Female 6. F2 Generation White-eyed Male 7. F2 Generation Wild-type Male 8. F2 Generation Purple-eyed Male 9.
