reversion

a process in which a MUTANT regains the WILD-TYPE PHENOTYPE. This may occur by, for example, a back mutation that precisely restores the wild-type DNA sequence and therefore the wild-type phenotype, or by a SUPPRESSOR MUTATION that restores only the original phenotype. The resulting organism is called a revertant. see REVERSE MUTATION.

reversion

1. a returning to a previous condition; regression.
2. in genetics, inheritance from some remote ancestor of a character that has not been manifest for several generations.
