question 4 of 25
why might a population fail to experience much variation in its traits over
time?
a. the environment remains stable.
b. the population has a large number of genes.
c. the population experiences a lot of competition with other
populations for resources.
d. the environment experiences drastic changes.

Explanation:

Step1: Analyze option A

If the environment is stable, there's no strong selective pressure.

Step2: Analyze option B

A large number of genes usually allows for more variation, not less.

Step3: Analyze option C

Competition for resources can drive variation as different traits may be favored.

Step4: Analyze option D

Drastic environmental changes create new selective pressures, promoting variation.

Answer:

A. The environment remains stable.
