Allelism
Definition
The state, property, or biological phenomenon whereby a gene possesses multiple alternative forms or mutant variants (alleles) occupying the same locus on homologous chromosomes. Structurally, this concept underscores genetic diversity within a population, analyzed in Mendelian inheritance studies to explain the functional interactions between phenotypic traits transmitted to offspring.
