Question

question 9 of 10
the curve on the left shows the height of a population of penguins. the curve on the right shows the population five years later. what has happened to this population?
a. stabilizing selection
b. polygenic selection
c. directional selection
d. disruptive selection

Explanation:

Disruptive selection favors extreme phenotypes. In the given curves, the initial single - peaked distribution (likely representing an intermediate phenotype) splits into a distribution with a peak towards the higher height range. This indicates that extreme phenotypes (in this case, taller penguins) are being selected for, which is characteristic of disruptive selection. Stabilizing selection would narrow the distribution around the mean. Directional selection would shift the peak in one direction. Polygenic selection is not a standard term for this type of evolutionary selection pattern.

Answer:

D. Disruptive selection
