Definitions:

Selection

The process by which certain traits become more or less common in a population due to their impact on the survival and reproduction of their carriers.

Trait

A specific characteristic or feature exhibited by an organism, which can be genetic, behavioral, or physical in nature.

Broad Sense Heritability

The proportion of the total phenotypic variance of a trait that is attributable to genetic variance, where genetic variance is represented in its entirety as a single value (that is, genetic variance is not broken down into different components).

Narrow Sense Heritability

Narrow sense heritability is a measure of the proportion of phenotypic variance in a trait that can be attributed to additive genetic variance among individuals in a population.
