Balancing Selection

Frequency-Dependent Selection

A selection process where the fitness of a phenotype depends on its frequency relative to other phenotypes in a given population.

Inbreeding

The breeding of closely related individuals, increasing the chance of offspring inheriting genetic recessive traits.
