Question

In a population of woolybeasts, individuals with long snouts tend to survive better on an island that has burrowing termites. Over time, the woolybeast population consists of individuals with extremely long snouts. This is an example of:__________

A. stabilizing selection
B. directional selection
C. disruptional selection

Answer 1

Directional selection

Step-by-step explanation:

In direction direction, one extreme is selected ( individuals with long snouts) resulting in the trait distribution of the population to shifting toward the other extreme. thank me later kids.

Answer 2

The correct answer is A. stabilizing selection

Step-by-step explanation:

Stabilizing selection is one type of natural selection that occurs when the population having non-extreme traits are stabilized. It results in overexpression of a particular trait in a population. Here most average individual gets selected.

So as the stabilizing selection favors the middle phenotype and not extreme phenotypes it decrease the genetic variation. So here individuals who are having extremely long snout are selected therefore a particular trait is selected and overexpressed in the population. So it is an example of stabilizing selection.
