Question

reading check describe what are two circumstances under which genetic drift may occur?

Explanation:

Answer:

1. Founder effect: When a small group of individuals separates from a larger population to establish a new population in a different area, the genetic makeup of the new - founded population is a random sample of the original population's genes.
2. Bottleneck effect: A drastic reduction in population size due to events like natural disasters, disease outbreaks, or human - caused activities. This reduces the genetic variation in the population as only a random subset of the original population's genes survive.
