[Allelic isozymes].

Allelic isozymes or allozymes, are the products of allelic genes of paternal and maternal origin at the same locus. They can be identified by electrophoresis. From the technical easiness of electrophoretic detection, allozymes are used for the identification of individuals in population study. Amino acid and nucleotide sequence analyses of allozymes and their genes have provided a powerful tool for molecular evolutionary genetics and molecular systematics.
