Allelic
Allelic (pronounced: /əˈliːlɪk/) is a term used in Genetics to describe one or several forms of a gene, located at the same position, or locus, on a chromosome.
Etymology
The term "Allelic" is derived from the Greek word "allelon" which means "of each other". It was first used in the context of genetics in the early 20th century.
Definition
In Genetics, an allele is one of two or more versions of a gene that are found at the same place on a chromosome. Alleles can result in different traits, such as variations in eye color, hair color, and other characteristics. Each human has two copies of each gene, one inherited from each parent. These copies may be the same allele or different alleles.
