Assume that a widow's peak (a downward point in the hairline at the center of the forehead) is caused by a single gene. The widow's peak isdominant. Suppose a man and a woman who both have a widow's peak have children. Ifboth the man and the woman are heterozygous, probabilistically speaking, how many of their children will have a widow's peak? Fill in the cells in the Punnett square to help you. Use the letter "W" for the widow's peak gene.
