Trait Variability

The degree to which individuals differ from one another in terms of specific characteristics or traits.

Genetic Inheritance

The process by which genetic information is passed on from parents to their offspring, determining traits.

Genetic Coefficient

A measure that quantifies the contribution of genetic differences to differences in a trait among individuals.
