A male Drosophila homozygous for puny wing, brown eyes, and black cuticle all recessive autosomal alleles is mated to a female homozygous wild type. F1 females are then testcrossed, and the following phenotypes are observed in F2, in equal proportions: (puny wing, brown eyes, black cuticle), (puny wing, red eyes, wildtype cuticle), (big wing, brown eyes, black cuticle) and (all wildtype). Which of these genes are linked? Puny wing and brown eyes are linked; black cuticle is unlinked Brown eyes and black cuticle are linked; puny wing is unlinked Puny wing and black cuticle are linked; brown eyes is unlinked All three genes are linked None of these genes are linked (all three genes assort independently).
