IV. On offsprings of a diploid intersexual plant involved chromosome-fragments.

Abstract

(1) It is supposed that, in the male-intersexual plant used for this study, the chromosome fragments have no effect upon the sex-disturbance. The sex-disturbing-genes will be carried on certain autosomes, as in the ease of the other male-intersexual plants already studied by the author.
(2) In the somatic cells of the same individual in which the chromosome-fragments are involved, the number of chromosome-fragment is very variable. The cause of this phenomenon is explained in various ways.
