#allele

• Allele — One of the alternative forms or molecular variants of the same gene, structurally located at the same locus on a homologous chromosome. Alleles determine different variations of the same phenotypic trait (such as eye color or blood type), interacting with each other through relations of dominance, recessiveness, codominance, or incomplete dominance within diploid organisms.
• Alleles — 1. The plural form of the feminine noun alelă; the totality of alternative forms of the same gene occupying a specific chromosomal locus. 2. A regional, shortened, or familiar variant for the feminine plural demonstrative pronoun of distance 'acelea' (or 'acele'), used colloquially to indicate objects or persons located at a distance.
• Of the allele — 1. The genitive-dative singular form of the feminine noun alelă, used to express possession or attribution of a genetic trait specific to a certain variant of a gene. 2. A regional, popular, or shortened form for the oblique cases of the feminine plural demonstrative pronoun of distance 'acelei' (or 'acelor'), used colloquially in possessive structures.
• The alleles — The definite articulate plural form of the feminine noun alelă; it specifically and directly defines the alternative variants of the same gene occupying a homologous chromosomal locus, viewed as clearly defined objects of study within a diploid organism or a biological population.
• Allelo-generating — Determining, stimulating, or responsible for the formation and development of alternative variants of the same gene (alleles); relating to biochemical or mutagenic factors that induce structural variability at the same chromosomal locus. In molecular studies, the term describes an agent or cellular process capable of altering the original nucleotide sequence, leading to the emergence of new allelomorphic forms.
• Allelogenesis — The evolutionary or biochemical process of formation, emergence, and differentiation of alternative forms of a gene (alleles) within the gene pool of a species. Structurally, allelogenesis occurs through point mutations, gene duplications, or successive molecular recombinations, constituting the primary source of gene polymorphism and variability upon which natural selection acts.
• Allelomorph — 1. One of the alternative forms or molecular variants of the same gene, occupying the same locus on a homologous chromosome and controlling different variations of the same phenotypic trait; an allele. 2. Presenting allelomorphic characteristics, structures, or properties, belonging to a pair of alternative genes that interact through relations of dominance or recessiveness.
• Allozygote — A diploid organism or cell (zygote) in which the two alleles at a specific gene locus originate from completely independent and distinct ancestors, lacking a recent common origin (identical by state, but not by descent). This structural mechanism opposes the concept of an homozygote by descent (autozygote), serving as a baseline indicator of genetic variability and the absence of inbreeding within a population.
