Question

question 6
genetic drift is the result of ___________.
natural selection
a large gene pool
environmental variation
chance

Explanation:

Genetic drift is a mechanism of evolution that occurs due to random sampling of alleles. It is not driven by natural selection (which is based on fitness), a large gene pool (which reduces its effects), or environmental variation (which is more related to natural selection). It is simply a result of chance events, like a small group being isolated (founder effect) or a disaster reducing population size (bottleneck effect), where allele frequencies change randomly.

Answer:

chance
