Question

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?
Responses

a
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.

c
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 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 make its wool curly.

Answer 1

c

Explanation: The lamb got one allele from each parent. The mother (straight) is likely homozygous recessive, so the lamb must have inherited a curly (dominant) allele from the father and a straight (recessive) allele from the mother; that allele combination (and the proteins it encodes) produces curly wool.
