12. Consider a population of 5000 garter snakes. Two hundred of those snakes split off from the population to a new habitat. When the original population dropped from 5000 to 4800, the allele frequencies of various genes changed. The evolutionary process that caused the change in allele frequencies in the original population is:

The question is incomplete as it does not have the options which are-

a. migration

b. genetic drift

c. mutation

d. stabilizing selection

Answer:

The correct answer will be option - migration

Explanation:

Migration refers to the long-distance movement of the individual, group and population. The migration enables the flow of genes from one population into another called gene flow. Migration is the strongest force of gene flow after selection.

In the given case, since the allele frequency of the population has changed due to the migration of the 200 snakes from a population of 5000 snakes, therefore, migration is the correct answer.
