These tables, and Fig. 23 which has been constructedfrom them, show that two races have been produced bythe selection and self-fertilization of the extreme variants. Antirrhinuni Majus Striatum. 129 One of them, A, consists almost solely of finely stripedindividuals and contains no red ones. The other, B,consists almost entirely of broadly striped ones togetherwith 11-36% of uniformly red ones. But the separationis not nearly so sharp as between the striped on the onehand and the red on the other, inasmuch as the twocurves Fig. 23. AntirrJiinum majus hitciim rtthro-striatum.

For the signification ofg, s, b, R, see previous figure. We now come to the most important part of the ex-periment, the question of the inheritance of the redcharacter. On account of this greater importance I hadalready given it previously much attention. Here we are concerned not merely with the inheri-tance of the red flowers in general, but with the studyof the special cases already distinguished. First we haveto consider the red seed variants, then the bud-variantsand la
