The parents do not have widow's peaks, which means they must be homozygous recessive (ww). The only way their child can have a widow's peak is if they inherit the dominant allele (W) from one of the parents. Therefore, the probability of the child having a widow's peak is 50%.
Answer: 50%
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?
