3. In fruit flies, the gene for wing shape has an unusual allele called 'curly (designated cy). The normal(wld type) allele is designated 'cy.' A fly homozygous for cy (cy cy) has normal, straight wings. The heterozygote (Cy cy) has wings which curl up on the ends (and, incidentally, can't really fly). The homozygote for the Cy allele (Cy Cy) never hatches out of the egg. In other words, this allele is lethal in the homozygous condition. If two curly winged flies are mated, and the female lays eggs, predict the following, showing appropriate work: a. How many eggs will produce living offspring? b. How many straight winged flies do you expect among the living offspring? c. What percentage of the living offspring do you expect to be curly winged like the parents? Show your solution.
