2. The return to the original phenotype, either by reinstatement of the original genotype (true reversion) or by a mutation at a site different from that of the first mutation, which cancels the effect of the first mutation (suppressor mutation).
[L. reversio (see reversal)]

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.

Q. I have been struggling with an eating disorder. Can I reverse this? Hi everybody! Here is Tom of 25 yrs old male. I have been struggling with an eating disorder. Now I have low bone density into the osteoporosis level. My level is -2.6. I'm still young, is there hope for me? Can I reverse this? Are there any herbs or other supplements that may help me?
