Question

The inheritance of eye color in Drosophila is controlled by genes on each of the fly?s four chromosome pairs. One eye-color gene is on the fly?s X chromosome, so the trait is inherited in a sex-linked manner. For this sex-linked trait, the wild-type (brick red) allele is dominant over the mutant vermilion (bright red) allele. A homozygous wild-type female fly is mated with a vermilion male fly. X+ X+ * X^p Y Predict the eye colors of F1 and F2 generations. (Assume that the F1 flies are allowed to interbreed to produce the F2 generation.) Drag the correct label to the appropriate location in the table. Labels can be used once, more than once, or not at all. See the picture for the whole question

Explanation / Answer

F1 females: all wild type F1 males: all wild type F2 females: all wild type F2 males: 1/2 wild type; 1/2 vermillion
