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.
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. If both parents are heterozygous (Ww), there is a 75% chance that any one of their offspring will have a widowâs peak (see figure).
