heterozygous recessive

Answer 1

In genetics, a widow's peak is typically considered a dominant trait. If both the mother and father are homozygous dominant for a widow's peak (which means both have the genotype WW), then all their offspring will also be homozygous dominant (WW) for the widow's peak trait.

Since the question states that the child has a widow's peak, and both parents are homozygous dominant (WW), this scenario is an example of homozygous dominant since the child will inherit a dominant allele (W) from each parent.

Therefore, the correct response is homozygous dominant.
