A widow's peak is a dominant physical trait where the hairline dips into a V-shape near the center of the forehead. The expression comes from the belief that it was a sign of early widowhood, though the trait has also been considered a mark of beauty.
To determine the probability of inheritance of a widowâs peak (or any other dominant trait), the genotypes of the parents must be considered. For example, if one parent is homozygous dominant (WW) and the other is homozygous recessive (ww), then all their offspring will be heterozygous (Ww) and possess a widowâs peak.
