The revertants Hall found fell into three different classes (I, II and III). Class III grew the fastest (wild type rate), Class II grew slower and class I grew the slowest.

Pseudorevertant
A revertant that retains the original mutation but has a second mutation at a different site that partially or fully restores the wild-type phenotype. See suppressor.

Immortal revertant clones also appeared among senescent cells maintained in MX medium to retain introduced chromosome. These revertant clones seem to arise due to deletions in donor chromosomes.

making it unable to synthesize the amino acid histidine (His) from the ingredients in its culture medium. However, some types of mutations (including this one) can be reversed, a back mutation, with the gene regaining its function. These revertants ...
