Refer to the following figure depicting fly genetic crosses.Which actual result indicates that the genes for body color and wing length in fruit flies are linked?

Question

Quizplus · Accepted Answer

A low percentage of nonparental genotypes is present in the offspring, which suggests that the genes for body color and wing length in fruit flies are linked. This is because if the genes were not linked, we would expect a 1:1:1:1 ratio of the four possible phenotypes, but in this case, the nonparental genotypes are present in a lower percentage, indicating that the genes are likely linked.
