One is to present some new facts of inheritance obtained from pedi¬ gree cultures of maize; the other is to discuss the hy¬ potheses to which an extension of this class of facts naturally leads. This discussion is to be regarded simply as a suggestion toward a working hypothesis, for the facts are not sufficient to support a theory. They do, however, impose certain limitations upon speculation which should receive careful consideration. The facts which are submitted have to do with inde¬ pendent allelomorphic pairs which cause the formation of like or similar characters in the zygote. Nilsson-Ehle^ has just published facts of the same character obtained from cultures of oats and of wheat. My own work is largely supplementary to his, but it had been given these interpretations previous to the publication of his paper. In brief, Nilsson-Ehle's results are as follows: He found that while in most varieties of oats with black ^ Contributions from the Laboratory of Genetics, Bussey Institution, Har¬ vard University, No. 4.
