- . As we learned in this chapter, the white mutation ofDrosophila studied by Thomas Hunt Morgan isX-linked and recessive to wild type. When truebreeding white-eyed males carrying this mutationwere crossed with true-breeding purple-eyed females,all the F1 progeny had wild-type (red) eyes. When theF1 progeny were intercrossed, the F2 progeny emergedin the ratio 3/8 wild-type females: 1/4 white-eyedmales: 3/16 wild-type males: 1/8 purple-eyed females:1/16 purple-eyed males.a. Formulate a hypothesis to explain the inheritanceof these eye colors.b. Predict the F1 and F2 progeny if the parental crosswas reversed (that is, if the parental cross wasbetween true-breeding white-eyed females andtrue-breeding purple-eyed males).2. In the following types of matings, the phenotypes of the parents are listed together with the frequencies of phenotypes occurring among their offspring.
