'ww'
Explicación
## Step 1In genetics, a dominant trait is one that is expressed even when only one copy of the gene is present. This is represented by a capital letter. In this case, the dominant trait is the Widow's peak, represented by the letter 'W'.## Step 2A recessive trait, on the other hand, is only expressed when two copies of the gene are present. This is represented by a lowercase letter. In this case, the recessive trait is not having a Widow's peak, represented by the letter 'w'.## Step 3Given that the Widow's peak is dominant, a person without a Widow's peak would need to have two copies of the recessive gene, 'w'. This is because the presence of a dominant gene (W) would result in the expression of the dominant trait (Widow's peak).## Step 4Therefore, the genotype that would produce a person without a Widow's peak is 'ww'.
