2. In Drosophila, an X-linked recessive mutation, scalloped (sd), causes irregular wing margins. What F? and F? results if (a) a scalloped female is crossed with a normal male; (b) a scalloped male is crossed with a normal (homozygous) female?

Step 1
All of the male offspring will have scalloped wings because they inherit the X chromosome with the scalloped mutation from their mother and a Y chromosome from their father. Show more…

In Drosophila, an X-linked recessive mutation, scalloped (sd) causes irregular wing margins. Diagram the $F_{1}$ and $F_{2}$ results if $(a)$ a scalloped female is crossed with a normal male; (b) a scalloped male is crossed with a normal female. Compare these results with those that would be obtained if the scalloped gene were autosomal.

Assume a gene for warped wings (Wp) in Drosophila is dominant and X-linked. Wp+/Wp+ are wild type. And this is a rare case that homozygous WpWp flies are not lethal. Give the expected genotype and phenotypic ratios for the progeny of each of the following: 1. Warped male crossed with normal female 2. Warped heterozygous female crossed with normal male 3. Warped heterozygous female crossed with warped male 4. Warped homozygous female crossed with normal male
