Allele (Anthromorphemics)

An alternate form of a gene.

Allele (Anthropology)

An alternate form of a gene.

Allele (Autism)

One of two or more variations of a gene that can occupy the same position (locus) on a chromosome.

Allele (Bioinformatics)

A given form of a gene that occupies a specific position or locus on a chromosome. Variant forms of genes occurring at the same locus are said to be alleles of one another.

Allele (Biotechnology)

One of several alternate forms (DNA sequences) that resides at the same locus on the chromosome and controls the same phenotype (although with potentially differing effects).

Allele (Canine)

One member of a pair or series of genes that occupy a specific position on a specific chromosome.

Allele (Dairy Production)

One of two (or more) forms of a gene that exist at a single location on a chromosome and result in different phenotypes.

Allele (Evolution)

One of the alternative forms of a gene. For example, if a gene determines the seed color of peas, one allele of that gene may produce green seeds and another allele produce yellow seeds. In a diploid cell there are usually two alleles of any one gene (one from each parent). Within a population there may be many different alleles of a gene; each has a unique nucleotide sequence.

Allele (Fish)

An alternate form of a gene.

Allele (Fossils)

One of the alternative forms of a gene. For example, if a gene determines the color of eyes, one allele of that gene may produce brown eyes and another allele produce blue eyes. In a diploid cell there are usually two alleles of any one gene (one from each parent). Within a population there may be many different alleles of a gene; each has a unique nucleotide sequence.

Allele (Gaucher Disease)

Any one of two or more genes occupying the same locus (precise location) on a chromosome, determining a given characteristic, such as eye color.

Allele (Genetics)

One of many possible forms of a given gene. Different alleles produce variation in inherited characteristics such as hair and eye color. In an individual, one form of an allele may be expressed (dominant) while the other form may be masked (recessive).

Allele (Genetics and Genealogy)

One of the variant, alternative forms of a gene, nucleotide, or non-gene DNA sequence pattern, at a particular locus (location), on a chromosome. Different alleles, if located in a gene produce variation in inherited characteristics such as hair color or blood type or even diseases. In an individual, one allele (the dominant form) may be expressed more than another form (the recessive one). Different alleles of DNA sequences when not located in genes do not produce variations in inherited characteristics or diseases. Mutations when they occur outside the gene areas do not affect the survival, function, or characteristics of the organism and thus are easily passed along in the DNA replication process for many generations with no effect on the organism. But these different alleles (different nucleotides or different DNA sequence patterns) found at certain known locations in the genome DNA sequence can be used to easily tell one DNA genome from another. The term allele is commonly used in Genealogy by DNA in referring to test results in non-gene areas of the genome to mean the sequenced base (A, T, C, or G) letter character symbol of a DNA nucleotide at a specific nucleotide known location in the genome DNA sequence, the specific DNA sequence pattern at a specific known location in the genome DNA sequence, or the numeric value of the number of repeats of a particular repeating DNA sequence pattern at a certain known location in the genome DNA sequence. See DYS, SNP, STS, Mini-Satellite, Micro-Satellite, and STR.

Allele (Genome)

Alternative form of a genetic locus; a single allele for each locus is inherited from each parent (e.g., at a locus for eye color the allele might result in blue or brown eyes).
See also: locus, gene expression

Allele (Gerontology)

An alternative form of a gene.

Allele (HIV and AIDs)

An alternate form of a specific GENE on a chromosome. Each allele is an individual member of a gene pair and is inherited from one parent.

Allele (Horse Health)

An alternative form of a given gene. For each gene there are two alleles, one on each chromosome of a chromosome pair. One allele is inherited from the mother, the other from the father.

Allele (Huntingtons Disease)

One of the different versions of a gene. All alleles for a particular gene code for the same trait, but they influence the trait in different ways. For example, different alleles for the hair color gene correspond to different hair colors.

Allele (Lissencephaly)

A gene found in the same location on a pair of homologous chromosomes

Allele (Microbiology)

An allele is one of the alternative (two or more) forms of a particular gene inherited separately from each parent; usually found at the same locus on homologous chromosomes. Equivalent genes in the two sets might be different, for example because of single nucleotide polymorphisms.

Allele (Physical Geography)

Alternative forms of a gene. Each form produces a unique inheritable characteristic.

Allele (Pompe Disease)

One or more alternate forms of a gene that occupies a single location (also known as a locus) on a chromosome. For example, the gene for blue eye color and gene for brown eye color are two alleles of the gene for eye color.

Allele (Prader-Willi Syndrome)

One of two or more alternative forms of a gene occupying corresponding sites (loci) on partner chromosomes.
