In hogs a gene that produces a white belt around the animal's body is dominant over its allele for a uniform body. Another independent dominant gene produces fusion of the hoof (syndactyly). Suppose a uniformly colored hog homozygous for syndactyly is mated with a normal footed hog homozygous for the belted character. What would be the phenotype of the F1? If the F1's interbreed, what would be the phenotypic ratio of the F2?

Flower position, stem length, and seed shape were three traits that were studied by Mendel. Each is controlled by an independently assorting gene. If a plant that is heterozygous for all three traits was allowed to self- fertilize, what proportion of the offspring would be expected to show all three dominant phenotypes?
