Question

conclusion questions: look back at the examples and answer the following questions in complete sentences 6.) a square jaw is recessive to a round jaw (dominant). is it possible for two parents with a square jaw to have a child with a round jaw? why or why not?

Explanation:

Since square jaw is recessive, parents with square jaw must have two recessive alleles. Offspring inherit one allele from each parent. So, all offspring will have two recessive alleles (square jaw).

Answer:

No, it is not possible. Because parents with square jaw (recessive trait) have only recessive alleles to pass on. Their child will inherit two recessive alleles, resulting in a square jaw, not a round jaw (dominant trait which requires at least one dominant allele).
