Unformatted text preview: female with brown eyes and short wings is crossed to a male from a normal pure line, the F1 progeny consists of normal females and short winged males. If an F2 is produced by intercrossing the F1 males and females predict the fraction of F2 progeny that will have red eyes and short wings. Since males are the only sex affected by the short wing mutation, the inheritance is X-linked. The mutation causing the brown eyes is autosomal recessive The fraction of flies that have red eyes will be (3/4) The fraction of flies with short wings will be The faction of flies with both phenotypes is (3/4) x (1/2) = 3/8...
