To determine whether a particular trait is autosomal or sex-linked, scientists or breeders would perform reciprocal crosses. In a species of exotic bird, the wild-type glossy green is dominant over the yellow plumage. Assigning Ye+ to the wild type glossy green and Ye to yellow, show how you would perform such a cross (or crosses) to test the hypothesis that these plumage phenotypes in this exotic bird are sex-linked. What are the expected phenotypic ratios of the F2, after intercrossing the F1 in each case, if this trait is indeed sex linked?
