Question

A widow’s peak is dominant over a straight hairline. The genotypes of the offspring are WW, Ww, ww, and ww. A widow’s peak is dominant over a straight hairline. The genotypes of the offspring are WW, Ww, ww, and ww. What are the phenotypes of the offspring? 2 widow’s peak, 2 straight hairline 3 widow’s peak, 1 straight hairline 1 widow’s peak, 3 straight hairline 4 widow’s peak, 0 straight hairline

Answer 1

Based on genetics, the phenotypes of the offspring with genotypes WW, Ww, ww, and ww would be 3 widow's peak and 1 straight hairline because the widow's peak trait is dominant.

Step-by-step explanation:

The question regarding a widow's peak being dominant over a straight hairline and the resulting phenotypes given the genotypes WW, Ww, ww, and ww can be answered using basic principles of genetics. Since a widow's peak (W) is dominant over a straight hairline (w), individuals with genotypes WW and Ww will exhibit the dominant phenotype of a widow's peak. Only individuals with the genotype ww will exhibit the recessive phenotype of a straight hairline. Therefore, the phenotypes of the offspring will be 3 widow's peaks, and 1 straight hairline, as the genotypes WW and Ww (two instances of Ww are given) all correspond to the dominant trait.

I think it is A but I just doing the exam right now
