Glossary Term Revertant
Definition An individual carrying an allele of a given gene that at one time produced a mutant phenotype, but which since has undergone a subsequent mutation that restored a wild-type phenotype. The mutation need not restore the gene to its original nucleotide sequence to be considered a reversion event.
