At the level of the phenotype,natural selection influences the
A) distribution of alleles.
B) distribution of quantitative traits.
C) distribution of genotypes.
D) distribution of alleles and distribution of genotypes.
E) None of these

Accepted Answer

Natural selection influences the distribution of quantitative traits, which are traits that vary continuously and are influenced by both genetic and environmental factors. Natural selection acts on the variation in these traits and favors certain variants over others, leading to changes in the frequency of alleles that contribute to the variation. However, it does not directly influence the distribution of genotypes or alleles themselves.
