In German cockroaches, a curved wing (cv) is recessive to a normal wing (cv+). A homozygous cockroach that has normal wings is crossed with a homozygous cockroach that has curved wings. The F1 are intercrossed to produce the F2. Assume that the pair of chromosomes containing the locus for wing shape is metacentric. Draw this pair of chromosomes as it would appear in the parents, the F1, and each class of F2 progeny at metaphase I of meiosis.
