In the fruit fly Drosophila melanogaster, vestigial wings, and hairy body are produced by two recessive genes located on different chromosomes. The normal alleles, long wings, and hairless body are dominant. a). Suppose a vestigial-winged hairy male is crossed with a homozygous normal female. What types of progeny would be expected? b). If the F1 from this cross are permitted to mate randomly among themselves, what progeny would be expected in F2? Show complete genotypes, phenotypes, and ratios for each generation. c). Suppose a hairy female, normal wing (heterozygous for wing) is crossed with a vestigial-winged, normal body (heterozygous for hairy body) male. Give offspring genotypic and phenotypic ratios.
