decide which examples are most likely to increase variation or decrease variation. some examples could do both. which of the following could possibly increase genetic variation indirectly?\ntoxins\npredator - prey relationships\ncompetition\nnew habitat\ndisasters\nincreased food supply
Answer
Brief Explanations:
Toxins can cause mutations directly. Predator - prey relationships, competition, new habitat, disasters, and increased food supply can indirectly affect natural selection. Natural selection can lead to changes in allele frequencies over time, which can increase genetic variation in a population. For example, a new habitat may present new selective pressures that favor different traits, leading to increased genetic variation as the population adapts.
Answer:
predator - prey relationships, competition, new habitat, disasters, increased food supply
