C. Populations that experience a lot of environmental change tend to experience fewer changes in their traits over time.
D. In environments that experience very little change, a population's traits tend to change over time.

Genetic and environmental factors play a key role in determining the variations in traits within a population through mechanisms like natural selection, genetic drift, gene flow, and mutations.

Explanation:

Genetic and environmental factors contribute to the variations in traits within a population. Alleles can lead to different phenotypes, while environmental changes can also influence individual characteristics. Natural selection, genetic drift, gene flow, and mutations play crucial roles in shaping the traits present in populations over time.
