In the F₂ generation of Mendel's monohybrid crosses, the 3:1 ratio refers to: A)single-nucleotide polymorphisms (SNPs). B)copy-number variations (CNVs). C)variable number of tandem repeats (VNTRs). D)genotypes. E)phenotypes.

Question

Quizplus · Accepted Answer

The 3:1 ratio in Mendel's monohybrid crosses refers to the ratio of phenotypes observed in the offspring of the cross. Specifically, the ratio indicates that three-quarters of the offspring exhibit one phenotype (e.g. dominant trait) and one-quarter exhibit the other phenotype (e.g., recessive trait). Therefore, the best choice for this question is E, "phenotypes."
