When allele pairs are the same, they are homozygous. When the alleles of a pair are heterozygous, the phenotype of one trait may be dominant and the other recessive. The dominant allele is expressed and the recessive allele is masked. This is known as complete genetic dominance. the brain machine 1955

"WebAnother example occurs when the recessive allele is linked to an allele of a different gene that has a large fitness advantage — since recombination rarely separates the two alleles, this can result in the "bad" allele persisting or even increasing in the population.

WebMicroevolution is a change in the frequency of gene variants, alleles, in a population, typically occurring over a relatively short time period. Population genetics is the field of biology that studies allele frequencies in populations and how they change over time. Allele frequency refers to how common an allele is in a population.

Weballele, also called allelomorph, any one of two or more genes that may occur alternatively at a given site (locus) on a chromosome.
