Question

Some people have freckles, and some people do not have freckles. If a child has freckles, at least one parent has freckles. However, the child may have a sibling that does not have freckles. Which statement best describes the presence of freckles?

Answer 1

For this information to be true, that would mean freckles is a dominant trait, and to not have freckles is a recessive trait. So that means if even someone's genotype has both the freckle and the no freckle gene, their phenotype will be freckles.

Answer 2

The answer is B, there are two alleles for freckles.
