The 4 Allele

The "4 alleles" typically refer to the different versions of a gene found in a population. Genes are segments of DNA that determine traits, and alleles are the specific forms these genes take. Typically, an individual has two alleles for each gene, one from each parent. When there are four alleles in a population, it means multiple variant forms exist, increasing genetic diversity. This diversity can lead to a wider range of traits and can influence how traits are inherited and expressed in individuals, playing a crucial role in evolution and population genetics.
