In tomatoes, tall is dominant to short and smooth fruits are dominant to hairy fruits. A plant that is homozygous for both dominant traits is crossed with a plant that is homozygous for both recessive traits. The F1 progeny are test crossed with the following results: 78 tall smooth fruits; 82 short hairy fruits; 22 tall hairy fruits; and 18 short smooth fruits. These data indicate that the genes are:

In a species of Yeti (the Abominable Snowman, not the cooler/thermos company) Foot Size (big or small) is controlled by one gene, while Head Shape (round or lumpy) is controlled by different gene. Suppose that a big-footed lumpy-headed male Yeti mates with a small-footed round-headed female Yeti. 8 offspring result: 4 big-footed, round-headed Yeti and 4 small-footed, round-headed Yeti. (Assume that the parents are not necessarily homozygous for each allele.) If big feet (B) in Yeti were to be dominant to small feet (b), what would be the genotype of the big-footed parent with respect to the foot gene?
