Unformatted text preview: wild type. We were able to determine the mutations were X-linked by looking at the F2 progeny. All females in this group were wild type and the males had a large dispersal between the different mutations. Because none of the females had any of the mutations, we prove not only that it is X-linked, but also again that the mutations are recessive. The F2 females must receive an X from their fathers, and because there is no recombination in Drosophilia males, this X must be wild type. The F2 males, on the other hand, only receive the one X from their mother which has 8 possible recombinations resulting in 8 different phenotypes. 2....
