The term ________ selection is used to refer to situations in which genetic variance is maintained when both extremes of the same trait (e.g.,aggression vs.passivity)are favored to the same degree under different conditions.

Question

Quizplus · Accepted Answer

Balancing selection refers to situations where multiple alleles (versions of a gene) are maintained at high frequencies in a population instead of one allele being favored over the others. This can result in both extremes of a trait being favored to the same degree under different conditions, leading to genetic variance being maintained. In contrast, dynamic selection refers to situations where selection pressures change over time, adaptive selection refers to selection for traits that improve survival and reproduction, and evolutionary selection refers to the overall process of evolution by natural selection.
