Variation that does not alter the ability of an individual to survive and reproduce is therefore considered:

A) neutral.
B) genetic.
C) geographic.
D) heterozygous.
E) frequency-dependent.

Neutral Variation

Neutral variation involves genetic differences among individuals that do not confer a selective advantage or disadvantage in terms of survival or reproduction.

Genetic Variation

The diversity in gene frequencies within a population, resulting from mutations, genetic recombination, and other sources.

Geographic Variation

Genetic differences that may exist among different populations within the same species. See cline for an example of one type of geographic variation
