Consider the following scenario:

You notice that no two cats at the pet store are exactly alike. Some have spotted fur. Some have striped fur. Some have fur of one solid color.

What term is used to describe your observation?

A.fitness

B.selective pressure

C.variation

D.natural selection

C. variation

What statement accurately describes the relationship between variation and fitness?

Variation can influence fitness, as certain variations may make an organism better adapted to its environment and therefore have a higher fitness. However, not all variations necessarily impact fitness, and some may even decrease fitness. Ultimately, natural selection acts upon the variation present in a population to determine which traits are more or less fit for survival and reproduction.

The term used to describe your observation is "C. variation."
