When working out genetics problems in this and succeeding chapters, always assume that members of the P 1 generation are homozygous, unless the information or data you are given require you to do otherwise.
In Drosophila , gray body color is dominant to ebony body color, while long wings are dominant to vestigial wings. Assuming that the P 1 individuals are homozygous, work the following crosses through the F 2 generation, and determine the genotypic and phenotypic ratios for each generation.
(a) gray, long × ebony, vestigial
(b) gray, vestigial × ebony, long
(c) gray, long × gray, vestigial
