Question

(11.3) Why is genetic drift undesirable in a population?

X a. Harmful alleles may be formed by mutation in the new population.


b. A population with little variation is less likely to survive if the environment changes.

c. A small population is less likely to survive than a large population.

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

A is wrong ​

Answer 1

Answer:

Genetic Drift Decreases Gene Diversity and Leads to Population Subdivision. Alleles that occur at a low frequency are usually at a disadvantage in the process of genetic drift. Low-frequency alleles face a higher probability of disappearing from a population than alleles that occur at a higher frequency.

Answer 2

Answer:

Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error). Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations
