Absolute or relative fitness.

In biology, fitness is understood as the presence of the ability for self-reproduction of individuals that have a certain genotype. In the course of natural selection, less fit individuals with a unique genotype disappear.

Absolute fitness can be found by the ratio of the number of individuals with a specific genotype before and after selection.

Relative fitness is the average number of surviving offspring of individuals with a particular genotype compared to the average surviving offspring of individuals with a competing genotype.
