Definitions:

Selection Differential

Selection differential is a measure of the strength of phenotypic selection. The selection differential describes the difference between the mean of the reproducing members of the population that contribute offspring to the next generation and the mean of all members of a population.

Quantitative Trait

A measurable phenotype that varies among individuals over a given range to produce a continuous distribution of a phenotype. Quantitative traits are sometimes called complex traits; they’re also sometimes called polygenic traits because their variation can be attributed to polygenic effects (that is, the cumulative action of many genes).

Heritability

The proportion of variation in a trait among individuals that can be attributed to genetic differences.

Heritability

The proportion of observed variation in a particular trait that can be attributed to inherited genetic factors in a population.
