Apopulation of snakes that eat small rodents enters a new habitat. in the new habitat, there are many species of rodents,
and their populations are high because there are few natural predators.
what will most likely be the effect on the genetic variation of the snake population?

a. genetic variation will increase because of a selective pressure.
b. genetic variation will increase because of a new habitat and food source.
c. genetic variation will decrease because of a selective pressure.
d. genetic variation will decrease because of a new habitat and food source.

In the given case, the genetic variation will elevate due to the new habitat as well as a food source.

Further Explanation:

Genetic variation refers to the differences found in the DNA or deoxyribonucleic acid among the individuals. There are many sources of genetic variation which includes genetic recombination and mutation. It is possible to detect genetic variation from the observations of phenotypic variation in discrete or quantitative traits. Geographic variation refers to the genetic differences found in populations from different locations which can be caused due to genetic drift or natural selection. These variations within the population are commonly recorded as the percentage of gene loci which are known to be polymorphic or the percentage of gene loci in individuals that are heterozygous.

Food and the habitat are known to be the main facets which affect the genetic variation and when there is a reduction in the predators and elevation in food items, then the chances of more genetic variation in a population also elevates. In the given case, the snakes travel to a new habitat which has more food and fewer predators and eventually, the genetic variation of the population will elevate.
