Answer :
Final answer:
An individual with a widow's peak can have either a heterozygous (Ww) or homozygous dominant (WW) genotype, as they both contain the dominant 'W' allele necessary to exhibit the trait.
Explanation:
The trait for a widow's peak is a monoallelic dominant trait, meaning that an individual only needs one copy of the dominant allele to exhibit the trait. A widow's peak is represented by the allele 'W', and the absence of a widow's peak (a straight hairline) is represented by 'w'. Therefore, the correct genotypes for an individual with a widow's peak could be either heterozygous (Ww) or homozygous dominant (WW). These genotypes have either one or two copies of the dominant 'W' allele, both of which result in the presence of the widow's peak trait. An individual with the homozygous recessive genotype (ww) would not display a widow's peak but would have a straight hairline.
