Solution(By Examveda Team)

The reason behind reversion is Mutation.
Reversions are genetic alterations that reverse the effect of mutations. Some revertants are due to compensatory changes in genes different from the ones with the original mutation.
Reversion occurs when the effects of one mutation are counteracted by a second mutation. It refers specifically to phenotype.
