 Two goldfish have different parents. One fish has a split tail and the other does not. Why do the goldfish have tails with different shapes?

• Each goldfish has a different tail shape because offspring from different parents will have different tail shapes.

• Each goldfish has a different tail shape because they have different versions of the gene for tail shape that connect together to make different tail shapes.

• The goldfish have different versions of the gene for tail shape. The genes are split inside one goldfish’s tail but not inside the other’s.

• The goldfish have different versions of the gene for tail shape, which instruct for different proteins that connect in different ways to make different tail shapes.

A father sheep has curly wool while a mother sheep has straight wool. Which of these statements explains why one of their baby lambs has curly wool?

• The baby lamb inherited its copies of the gene for wool shape from its father and not from its mother. Just like its father’s genes, those genes instruct for proteins that connect in ways that make its wool curly.

• The baby lamb inherited its copies of the gene for wool shape from its father and not from its mother. Those genes connect together to make its wool curly.

• The baby lamb inherited one copy of the gene for wool shape from its father and one copy from its mother. That gene combination instructs for proteins that connect in ways that make curly wool.

• The baby lamb inherited one copy of the gene for wool shape from its father and one copy from its mother. Those genes connect together to make its curly wool.

In a group of rabbits, some individuals have black fur and others have brown fur. In this group, the gene for the fur color trait has two alleles. The allele F is for black fur, and the allele f is for brown fur.

Skeeter, a rabbit from this group, has brown fur. Skeeter has two alleles for brown fur.

Based on this information, what is Skeeter's phenotype for the fur color trait?

• black fur

• Ff

• ff

• brown fur
