ALLELE Meaning and
Definition
-
An allele, in genetics, refers to any of the alternative forms or variants of a specific gene locus found on a chromosome. Genes encode the instructions or information required to produce specific traits, characteristics, or proteins in living organisms. Each gene locus represents a specific location on a chromosome that contains two alleles, one from each parent. These alleles are responsible for the different versions or variations of a trait that an individual can possess.
Alleles can be dominant or recessive. A dominant allele is one that expresses itself and produces the associated trait regardless of the presence of another allele at the same gene locus. On the other hand, a recessive allele requires another allele identical to itself to produce the associated trait. In the presence of a dominant allele, a recessive allele may remain hidden or masked in an organism's phenotype.
The presence and combination of alleles in an individual determine the phenotype or physical characteristics observed in an organism. For example, in humans, the gene locus responsible for determining blood type has three alleles: A, B, and O. If an individual inherits the A allele from both parents, they will have type A blood. If they inherit the B allele from both parents, they will have type B blood. If they inherit the A allele from one parent and the B allele from the other, they will have type AB blood. Finally, if they inherit the O allele from both parents, they will have type O blood.

Etymology of ALLELE
The word "allele" was coined by Danish botanist Wilhelm Johannsen in 1903. It is derived from the Greek words "allelon", meaning "of each other" or "mutually", and "alellos", meaning "one another". Johannsen used this term to describe different forms of a gene that occur at the same position, or locus, on a chromosome pair. The term "allele" was specifically introduced to describe the alternative variants that determine the different traits or characteristics of an organism.
