Question

Describe the conditions under which each type of selection (stabilizing, directional, and disruptive) is likely to be found.

a) Taxonomy
b) Genetics
c) Ecology
d) Evolution

Answer 1

Stabilizing selection favors average phenotypes, directional selection favors extreme phenotypes, and disruptive selection favors phenotypes at both ends of the distribution.

Step-by-step explanation:

Stabilizing selection occurs when phenotypes at both extremes of the phenotypic distribution are selected against, narrowing the range of variation. This can be found in taxonomy, genetics, ecology, and evolution.

Directional selection occurs when one of two extreme phenotypes is selected for, shifting the distribution towards that extreme. This type of selection can be observed in genetics, ecology, and evolution.

Disruptive selection occurs when phenotypes in the middle of the range are selected against, resulting in two overlapping phenotypes at each end of the distribution. This type of selection can be found in taxonomy, genetics, ecology, and evolution.
