why is genetic drift undesirable in a population?

a) a small population is less likely to survive than a large population

b) harmful alleles may be formed by mutation in the new population

c) a population with little variation is less likely to survive if the environment changes

d) the bottleneck effect may cause destructive events to occur in the population

Respuesta :

The answer is A
Explanation: Small populations tend to lose genetic diversity more quickly than large populations due to stochastic sampling error (i.e., genetic drift). This is because some versions of a gene can be lost due to random chance, and this is more likely to occur when populations are small.
