Definition of allele. ... Examples: The gene for seed shape in pea plants exists in two forms, one form or allele for round seed shape (R) and the other for wrinkled seed shape (r). Organisms have two alleles for each trait. When the alleles of a pair are heterozygous, one is dominant and the other is recessive.

Genes and Alleles ... Not all copies of a gene are identical and alternative forms of a gene, called alleles, lead to the alternative form of a trait. Alleles are a way of identifying the two members of a gene pair which produce opposite contrasting phenotypes.

Allele frequency - Wikipedia, the free encyclopedia
Allele frequency is the proportion of all copies of a gene that is made up of a particular gene variant (allele). In other words, it is the number of copies of a particular allele divided by the numb...
en.wikipedia.org/wiki/Allele_frequency
An individual inherits two alleles for each gene, one from each parent. If the two alleles are the same, the individual is homozygous for that gene. If the alleles are different, the individual is heterozygous.

New alleles arise from existing ones by mutation. The diversity of alleles produced in this way is the basis for hereditary variation and evolution. The different alleles of a given gene determine the degree to which the specific hereditary characteristic controlled by that gene is manifested.
