Professor Weldon declares that Laxton’s “experience was altogether different from that of Mendel.” The reader will bear in mind that when Laxton speaks of fixing a variety he is not thinking particularly of seed-characters, but of all the complex characters, fertility, size, flavour, season of maturity, hardiness, etc., which go to make a serviceable pea. Considered carefully, Laxton’s testimony is so closely in accord with Mendelian expectation that I can imagine no chance description in non-Mendelian language more accurately stating the phenomena. Here we are told in unmistakable terms the breaking up of the original combination of characters on crossing, their re-arrangement, that at the fourth or fifth generation the possibilities of sporting [sub-division of compound allelomorphs and re-combinations of them?] are exhausted, that there are then definite forms which if selected are thenceforth fixed [produced by union of similar gametes?] that it takes longer to select some forms [dominants?] than others [recessives?], that there may be “mule” forms[144] or forms which cannot be fixed at all[145] [produced by union of dissimilar gametes?]. [144] For instance the _talls_ produced by crossing _dwarfs_ are such “mules.” Tschermak found in certain cases distinct increase in height in such a case, though not always (p. 531). [145] “The remarkably fine but unfixable pea _Evolution_.” Laxton, p. 37. But Laxton tells us more than this. He shows us that numbers of varieties may be obtained--hundreds--“incalculable numbers.” Here too if Professor Weldon had followed Mendel with even moderate care he would have found the secret. For in dealing with the crosses of _Phaseolus_ Mendel clearly forecasts the conception of _compound characters themselves again consisting of definite units_, all of which may be separated and re-combined in the possible combinations, laying for us the foundation of the new science of Analytical Biology. How did Professor Weldon, after reading Mendel, fail to perceive these principles permeating Laxton’s facts? Laxton must have seen the very things that Mendel saw, and had he with his other gifts combined that penetration which detects a great principle hidden in the thin mist of “exceptions,” we should have been able to claim for him that honour which must ever be Mendel’s in the history of discovery.
