Any of the alternative forms of a gene that are located together on a chromosome. For autosomal chromosomes, each allele will normally have two copies of the same gene, one inherited from the mother and one from the father.
There are usually two copies of a gene. These two copies are called alleles. In some cases, one or both, alleles will be mutated or altered in some way.
A specific form or possible version of a gene having multiple versions. Alleles may be dominant or recessive.
Most genes exist in two copies (one in inherited from the mother, one from the father). Genes reside on chromosomes. There are 22 pairs of “regular” chromosomes, and one pair of “sex”-determining chromosomes (males are XY; females are XX). For each chromosome pair, there are a series of genes that are paired (one copy of each gene being present on one of the matched chromosomes). Since we inherit one copy of each chromosome from each parent (and thus one copy of each of the genes lined up on the chromosome), we end of with 2 copies, or alleles, of each gene. Alternate forms of the same allele produce variations in the characteristics of inheritance such as, for example, eye color or blood type. If the paired alleles are identical they are said to be homozygous, if they are different they are heterozygous.
( allelomorph) Alternative form of a gene at a locus.
Any one of two or more genes occupying the same locus (precise location) on a chromosome, determining a given characteristic, such as eye color.

All individuals inherit one allele from each parent, but there may be numerous different alleles for a locus (protein coding area) in the world's population. Some alleles are advantageous and predominate, while others are not a occur less commonly.[close window
(a leel´) [Gr. allos: other] • The alternate forms of a genetic character found at a given locus on a chromosome.
The genetic variant of a gene. A gene can be found in different variants in a population, even in the same individual.

Alleles are also responsible for genetic diseases.

(pronounced UH-leel) - Used in genetic genealogy in reference to the scientific result for a marker.
In genetics, an allele (pronounced al-eel or al-e-ul) is any one of a number of viable DNA codings occupying a given locus (position) on a chromosome. Usually alleles are DNA (deoxyribonucleic acid) sequences that code for a gene, but sometimes the term is used to refer to a non-gene sequence. An individual's genotype for that gene is the set of alleles it happens to possess.
