an organism has two different possible traits, a and b. a graph of the population is shown right. which of the following statements is true about trait b? check all that apply. it decreased in frequency over time. it became extinct. it is carried on a recessive allele.

an organism has two different possible traits, a and b. a graph of the population is shown right. which of the following statements is true about trait b? check all that apply. it decreased in frequency over time. it became extinct. it is carried on a recessive allele.

Answer

Explanation:

Step1: Analyze the graph

By observing the graph for Trait B, we check its population - size changes over time.

Step2: Evaluate each statement

If the population - size of Trait B is going down over time, its frequency is decreasing. If the population - size reaches 0, it becomes extinct. There is no information in the graph to determine if it is carried on a recessive allele.

Answer:

It decreased in frequency over time. It became extinct.
