This is not so hard to believe, If 'Great Expectations' is the result of a 
mutation, in all probability the mutation occurred at ether one base or if 
more than one base -a few in one gene?  In any rate only a very small amount 
of the DNA changed. If that very small amount mutated back or some part of 
the original mutated bases reverted-then the resulting plant might be 
indistinguishable from the original Elegance.

The importance of a mutation is not in the amount of mutation  but were the 
mutation occurs.

In fruit fly studies they have changed hug sections of the DNA by using 
mutigens but you still end up with a fruit fly.  But small changes in the 
right spot on  just a few genes results in all types of diffrent changes.
