Question

as you have learned in the peppered moth example, species can react to environmental change.
which of the following most accurately explains why genetic diversity is related to a species reaction to environmental change?
a genetic diversity limits for varying traits that enable a species to adapt to changing environmental conditions.
b genetic diversity allows for varying traits that enable a species to adapt to changing environmental conditions.
c genetic diversity allows for the consistent response of individuals within a population to changing environmental conditions.
d genetic diversity limits a species ability to adapt to changing environmental conditions.

Explanation:

Genetic diversity means there are different genetic variations within a species. These variations lead to different traits. When the environment changes, some of these traits may be more suitable (e.g., in the peppered moth example, darker - colored moths were better camouflaged after industrial pollution darkened the trees). So genetic diversity provides the raw material (varying traits) for a species to adapt. Option A says "limits", which is incorrect. Option C about "consistent response" is wrong as genetic diversity leads to variation. Option D's "limits ability" is incorrect.

Answer:

B. Genetic diversity allows for varying traits that enable a species to adapt to changing environmental conditions.
