1. An experienced dog breeder has observed that to have any long-haired offspring, at least one of the parents must be a long-haired dog. Is long-hair dominant or recessive? Explain.

2. Refer to Table 14.1 of your text. When crossing true-breeding yellow seeded peas with true-breeding green seeded peas, the F1 generation all have yellow seeds. What phenotypic ratio would you expect in the F2 generation? What genotypic ratio would you expect?

3. Again referring to Table 14.1, a tall pea plant is crossed with a dwarf pea plant. What will be the phenotypic ratio if the tall pea plant was homozygous? What would be the phenotypic ratio if the tall pea plant was heterozygous?

4. Rabbits with the genotype CBCB are black, heterozygous rabbits CBCW appear brown, and rabbits that are CWCW have white fur. What is the phenotypic and genotypic ratio of the offspring of a cross between a brown and a white rabbit?
