Different molecular forms of an enzyme coded by different allelic forms of a gene.

A category of proteins often used as genetic markers because different alleles can often be readily by electrophoresis.

One of several possible forms of an enzyme that is the product of a particular allele at a given gene locus.

Alternative forms of an enzyme that have the same function, are produced by different alleles, and are often detected by protein electrophoresis.

allelic forms of an enzyme that can be distinguished by gel electrophoresis. Allozyme analysis is used to observe genetic variation from the gene products.
