Linkage Disequilibrium

Linkage disequilibrium exists for any two loci if the occurrence of an allele at one of the loci is nonrandomly associated with the presence or absence of an allele at the other locus.

Positively Selected Allele

A positively selected allele is a variant of a gene that provides an advantage to individuals in their environment, increasing its frequency in the population.

Directional Selection

Directional selection favors individuals on one end of the distribution of phenotypes present in a population.
