Is a widow's peak forehead hairline or a straight forehead hairline more dominate?

A widow's peak hairline, characterized by a V-shaped point at the center of the forehead, is often considered a dominant trait compared to a straight hairline. Genetic studies suggest that the widow's peak is influenced by a single gene with dominant alleles. Therefore, individuals with one or both copies of the widow's peak allele are more likely to express this trait, making it more prevalent in certain populations.
