What Is A Gene Allele?

Alleles are the variants of a gene that are located on the same place on a chromosome. Locus is the location on the chromosome where a gene is found.

A Allele: An allele is an alternate version of a gene. This is also known as a variant of a gene. They are caused by differences in the sequence of the DNA ...

For example, the gene for eye colour has an allele for blue eye colour and an allele for brown eye colour. For any gene, a person may have the same two alleles, ...

Each variation of a gene is called an allele (pronounced 'AL-eel'). These two copies of the gene contained in your chromosomes influence the way your cells work ...

The short answer is that an allele is a variant form of a gene. Explained in greater detail, each gene resides at a specific locus (location on a chromosome) ...

An allele is one of two or more versions of DNA sequence (a single base or a segment of bases) at a given genomic location.

Alleles are different versions of a gene, which vary according to the nucleotide base present at a particular genome location.

等位基因（allele）舊稱對偶基因，是同源染色體內同一個基因座上的多種表現形式；其在細胞有絲分裂時的兩個染色體上的基因座是對應排列的，故細胞遺傳學裡稱其為等位。

基因座上的DNA序列可能有許多不同的變化，各種變化形式稱為等位基因（allele）。基因座在基因組中的排列位置稱為基因圖譜（genetic map），基因作圖（gene mapping）則是測定基因座 ...
