Question

Genetic drift, where allele frequencies randomly change over time, is strongest in Populations. A. Predatory. B.migratory. C. Large. D. Small

Answer 1

Answer:

The correct answer is option D- Small population.

Explanation:

Genetic drift is a random process which changes the allele frequency of a population in a short period of time. This change in allele frequency causes evolution and the allele frequency change can either decrease or increase over time.

This process is generally affected by the population size as a small population will have large sampling error which will have the strongest changes in allele frequency and alleles will have a greater chance of loss.

Thus, option D- Small population is the correct answer.

Answer 2

Answer:

The correct answer is option D, that is, small.

Explanation:

A phenomenon in which the frequencies of alleles within a population get alter by chance alone as an outcome of sampling error from generation to generation is termed as genetic drift. It is a random process, which can result in huge modifications in populations over a short time duration.  

This random drift is a result of repeated small population sizes, extreme decline in the size of the population known as founder events and bottlenecks where a novel population emerges from a small number of individuals. The genetic drift results in the fixation of genotypes or alleles in the populations.
