He believes, indeed, that hybridization largely accounts for the origin of those variations which Darwin had been content to speak of as “spontaneous”, and which are recognized as the material with which natural selection works in developing new species. Mendelian Heredity The striking results in the production of new varieties through hybridization that Mr. Burbank had attained became known to horticulturists and biologists, and probably had an important share in preparing the world to look with interest on the experiments of the Austro-Silesian monk, Mendel, when the obscure report that this ex- perimenter had published as long ago as 1863 was rediscovered just at the close of the nineteenth century. Mendel, working chiefly with the garden pea, had paid attention (as we have already seen) to — a few conspicuous characters regarding which different races of garden peas differ. ; He had observed the mutual relations in the inheritance of such qualities as tallness versus [22]
