Answer :
Final answer:
Offspring with WW and Ww genotypes will have a widow's peak, as the 'W' allele is dominant for this trait. Those with the ww genotype will have a straight hairline, since they lack the dominant allele for the widow's peak.
Explanation:
The phenotypes of the offspring with different genotypes for a widow's peak can be predicted based on the dominance of the trait. A widow's peak is a dominant trait, indicated here by the capital letter 'W', while a straight hairline is recessive, indicated by 'w'. So, individuals with WW and Ww genotypes will exhibit the widow's peak phenotype, because the presence of a dominant allele 'W' is enough to express the trait. Individuals with the ww genotype will have a straight hairline, as they lack the dominant allele for a widow's peak. Therefore, the phenotypes of the offspring will be as follows:
- WW genotype: Widow's peak
- Ww genotype: Widow's peak
- ww genotype: No widow's peak (straight hairline)

Final answer:
The genotypes WW and Ww result in a widow's peak due to the dominant W allele, while the genotype ww results in a straight hairline due to the absence of the dominant allele.
Explanation:
A widow's peak is a dominant trait represented by the allele W, whereas a straight hairline is recessive and represented by the allele w. Given the genotypes WW, Ww, and ww for offspring, the corresponding phenotypes would be as follows:
- WW individuals would have a widow's peak since they have two dominant alleles.
- Ww individuals would also have a widow's peak because the presence of one dominant W allele is enough to express the trait.
- ww individuals would have a straight hairline, as they lack the dominant allele necessary to produce a widow's peak.
In summary, the presence of at least one dominant W allele results in a widow's peak, while the absence of the dominant allele (ww) results in a straight hairline phenotype.
