Base your answer on the graph below. It shows the percent of variation for a given trait in four different populations of the same species. The populations inhabit similar environments. In which population will the greatest number of individuals most likely survive if a significant environmental change related to this trait occurs? (1 point) Responses

Question

a. 2
b. 4
c. 3
d. 1

Answer 1

a. 2

Population 2 has the least variation for the given trait, indicating that the individuals within this population are more genetically similar for this specific trait. Therefore, if a significant environmental change related to this trait occurs, the individuals in Population 2 are more likely to have the necessary genetic adaptation to survive, as there are fewer individuals with less advantageous traits.
