Genetic reversion

Genetic reversion is a mutation that occurs when a mutant gene is reverted to wild type. This reversion is located in the same place of the first mutation, which reverses the modification made previously. Is important to refer that this process will alter the base that suffered mutation before, in other words, the base will be altered and will return to what was in the first place, in the exact same position. Reverse mutation is less common than the forward mutations.
