white (w), yellow (y), and cut (ct) are recessive X-linked traits. A yellow-bodied, white eyed female with normal wings is crossed with a male whose eyes and body are normal, but whose wings are cut. The F1 females were wt, while the F1 males had yellow bodies and white eyes. These F1 individuals mated and the phenotype of the F2 male progeny were tabulated as follows: Phenotypes Number Observed + ct y 9 w + + 6 w ct y 90 + + + 95 + ct + 422 w + y 376 + + y 1 w ct + 1 Calculate the interference.
