allele

allele The common shortening of the term ‘allelomorph’. One of two or more forms of a gene arising by mutation and occupying the same relative position (locus) on homologous chromosomes. When in the same cell, alleles may undergo pairing during meiosis. They may be distinguished by their differing effects on the phenotype. The existence of two forms of a gene may be termed ‘diallelism’, and that of many forms, ‘multiple allelism’. The commonness of an allele in a population is termed the ‘allele frequency’.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.

allele

allele (allelomorph) One of the alternative forms of a gene. In a diploid cell there are usually two alleles of any one gene (one from each parent), which occupy the same relative position (locus) on homologous chromosomes. These alleles may be the same, or one allele may be dominant to the other (known as the recessive), i.e. it determines which aspects of a particular characteristic the organism will display. Within a population there may be numerous alleles of a gene; each has a unique nucleotide sequence.
