Question

1. n fruit flies, normal wings (wild-type) are dominant to vestigial (small, limited functioning) wings. If a true-breeding wild-type male mates with a pure-bred vestigial winged female, what is the probability that any individual offspring will have vestigial wings?

Answer 1

In fruit flies, the dominant V allele produces long wings, whereas the recessive v allele produces vestigial wings. Thus, flies with the genotype VV or Vv will have long wings, and flies with the genotype vv will have vestigial wings.
