In the fruit fly, 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. Suppose a vestigial-winged hairy male is crossed with a homozygous normal female. What types of progeny would be expected? If the F1 generation from this cross are permitted to mate randomly among themselves, what progeny would be expected in the F2? Show complete genotypes, phenotypes and ratios for each generation.
