Allele. Definition. noun, plural: alleles. (genetics). One member of a pair (or any of the series) of genes occupying a specific spot on a chromosome (called locus) that controls the same trait. Supplement. For example, a pair of alleles controlling the same trait, i.e. eye color: one allele codes for blue eyes, another allele for brown eyes. In humans, simple traits such as eye color may be caused by the interaction of only one pair of alleles.
Diploid organisms have one copy of each gene (and, therefore, one allele) on each chromosome. If both alleles are the same, they and the organism are homozygous with respect to that gene.If the alleles are different, they and the organism are heterozygous with respect to that gene.llele. An allele (UK /ËaeliËl/ ËÃ¦liËl OR /us/), ÉËliËl or, allel is one of a number of alternative forms of the same gene or same genetic. Locus, sometimes different alleles can result in different observable phenotypic, traits such as different. pigmentation
