which of the following can typically decrease genetic variation?\ntoxins\npredator - prey relationships\ncompetition\nnew habitat\ndisasters\nincreased food supply

Answer

Brief Explanations:

Predator - prey relationships can lead to selective pressure reducing certain genetic variants. Competition can also eliminate less - fit genotypes. Disasters like floods or wildfires can cause population bottlenecks, decreasing genetic variation. Toxins may cause mutations increasing variation, new habitat can promote speciation and increased food supply may support more genetic diversity.

Answer:

B. predator - prey relationships, C. competition, E. disasters
