But 5, as much as S, pollen grains of Ss plants behave in a thrum way, while 5 pollen grains of 55 plants behave in a pin way. Thus, either o£ two different mechanisms of gene action with which we are familiar elsewhere can determine incompatibility. One acts directly through the haploid pollen grain; the other is imposed upon the pollen through the cytoplasm of its diploid parent.
