Definitions:

Deleterious Alleles

Deleterious alleles are variants of genes that negatively affect the fitness or survival of an individual carrying them.

Homozygosity

The state of having two identical alleles at a particular gene locus, leading to the expression of a specific trait.

Fixing Beneficial Allele

The process by which a beneficial genetic variation becomes established, or fixed, in a population, often leading to evolutionary advantages.

Starting Frequency

Refers to the initial proportion or occurrence rate of a particular genetic variant or allele within a population at the beginning of a specified period.
