Answer

Explanation:

Step1: Analyze the graph

We observe the population - time graph for Trait A and Trait B. Trait B's population line is decreasing over time while Trait A's is increasing.

Step2: Evaluate each option

  • A change in the environment between generations 10 and 30 likely favored Trait A as the population of Trait A starts to increase and Trait B starts to decrease during this period. There is no evidence from the graph that a genetic mutation occurred or that a recessive trait was eliminated specifically. Also, the environment did not favor Trait B as its population is decreasing.

Answer:

favored trait A
