In peppered moth populations, light, n dark months r selected 4 in different environments. Which type of selection is dis, n wut would a distrubtion curve 4 all peppered moths look like?

A ) Disuptive selection: 2 peakes @ da ectemes of da graph with a dip in da middle

B ) Stablizing selection, 2 peaks @ da extremems of da graph with a dip in da middle

C ) Disruptive selection: s tall, narrow peak in da center of da graph

In the case of peppered moth populations, the selection occurring is an example of disruptive selection. This type of selection occurs when two or more contrasting phenotypes are favored in different environments, leading to increased variation within the population.

For peppered moths, in environments that are light (such as those with light-colored trees) and dark (such as urban areas with soot-blackened trees), both light and dark phenotypes are favored while the intermediate coloration may be less advantageous.

Therefore, the correct option is:

A) Disruptive selection: two peaks at the extremes of the graph with a dip in the middle.

The distribution curve for the peppered moths would indeed show two distinct peaks corresponding to the light and dark morphs, with a lower frequency of intermediate-colored moths in the middle.
