Which process occurs when selection works against the extremes of a trait and favors the intermediate phenotype quizlet?
Disruptive selection occurs when both extreme phenotypes are favored, while individuals with intermediate phenotypes are selected against by something in nature.
What kind of selection will favor an intermediate phenotype?
Each type of selection contains the same principles, but is slightly different. Disruptive selection favors both extreme phenotypes, different from one extreme in directional selection. Stabilizing selection favors the middle phenotype, causing the decline in variation in a population over time.
Which kind of natural selection occurs when selection works against the extremes of a trait and favors the intermediate phenotype?
Stabilizing selection
occurs when natural selection favors the intermediate states of continuous variation.
What is it called when evolution favors the extremes of a phenotype?
The directional selection theory says that an extreme phenotype (characteristics or traits) is favored over other phenotypes and this causes the allele frequency (how often the variant of a gene shows up in a population) to shift over time in favor of the extreme phenotype.
