Genotypes: The genotypes of the given phenotypes are:
• wing bristles = s+ , s (no bristles)
• eye color = c+, c (black eyes)
• thoracic bristles = h+, h (no bristles)
Female = s c+ h+
Male = s+ c h
In the fruit fly, Drosophila melanogaster, a spineless (sp, no wing bristles) female fly is mated to a male that is claret (cl, dark eyes) and hairless (h, no thoracic bristles). Phenotypically wild-type F1 female progeny were mated to fully homozygous (mutant) males and the following progeny (1000 total) were observed.
hairless, claret, spineless
