Reversion 

(1) A synonym of atavism.

(2) In plants with various genotypic components (mottled-leaf plants, chimeras), the appearance of shoots that correspond to one of the components.

(3) In genetics, turning of a mutated gene to a gene of the initial type (reverse, or back, mutation). Like direct mutations, reversion may be spontaneous or artificially induced by various mutagens. The study of reversions in bacteria, bacteriophages, and other microorganisms has led to a better understanding of the mechanism of mutagenesis.
