Question

A classic example of selection in natural populations involves the peppered moth Biston betularia in England. Industrial gases killed the lichens and mosses on buildings, trees, etc., and soot deposited on the landscape. Dark-colored moths gained a selective advantage. In this case, one would say that there was selection against the light-colored moths.Which morph, light or dark, would have the highest fitness?

Answer 1

dark

Step-by-step explanation:

Biological Fitness refers to the ability of an organism to survive long enough for it to find a mate, reproduce, and have offspring. This being the case it can be said that dark morph would have the highest biological fitness in this scenario. This is because they have gained the selective advantage, which would allow them to better camouflage and survive longer.
