How did Bateson and Punnett's work with comb morphology in chickens differ from the dihybrid work of Mendel? A)They were working with sex-limited traits. B)Their F₂ offspring displayed 4 unique phenotypes, not the four combinations of two phenotypes expected in a Mendelian cross. C)½ of their combinations were lethal. D)The expression of their trait varied by the environment in which the chickens were raised.

Bateson and Punnett's work with comb morphology in chickens differed from the dihybrid work of Mendel because their F₂ offspring displayed 4 unique phenotypes, not the four combinations of two phenotypes expected in a Mendelian cross. This is due to the fact that the comb morphology trait is influenced by multiple genes, which interact in complex ways to produce the observed phenotypes.
