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?

The gene for tallness (T) is dominant over the gene for shortness (t) in pea plants. A homozygous dominant pea plant is crossed with a heterozygous pea plant, and 200 seeds are produced. Approximately how many of these seeds can be expected to produce plants that are homozygous dominant?

People who can roll their tongues contain a dominant allele for tongue rolling. If people do not contain the tongue rolling gene, then they cannot roll their tongue no matter how hard they try. Consider the following situation: If a homozygous dominant tongue roller mates with a homozygous recessive non-tongue roller, then what is the probability of the offspring inheriting the tongue rolling gene?
