Question

A widow's peak is a V-shaped area of the hairline in the center of the forehead. The allele for having a widow's peak is dominant to the allele for not having a widow's peak.

If two parents do not have widow's peaks, what is the probability that their child will have a widow's peak?

Answer 1

0%

Step-by-step explanation:

A widow's peak is a V-shaped point in the hairline in the center of the forehead. Hair growth on the forehead is suppressed in a bilateral pair of periorbital fields. Without a widow's peak, these fields join in the middle of the forehead so as to give a hairline that runs straight across.

Answer 2

None. Since it is dominant, both would have to show it to pass in on.
