The Neutral Zone Of Selective Advantage In The Neighbourhood Of Zero Is Thus So Narrow That Changes In The Environment, And In The Genetic Constitution Of Species, Must Cause This Zone To Be Crossed And Perhaps Recrossed Relatively Rapidly In The Course Of Evolutionary Change, So That Many Possible Gene Substitutions May Have A Fluctuating History Of Advance And Regression Before The Final Balance Of Selective Advantage Is Determined.

Although No Explanation Can Be Expected To Be Satisfactory, It Remains A Possibility Among Others That Mendel Was Deceived By Some Assistant Who Knew Too Well What Was Expected. This Possibility Is Supported By Independent Evidence That The Data Of Most, If Not All, Of The Experiments Have Been Falsified So As To Agree Closely With Mendel's Expectations.
