Radiation and the sex ratio in man.
An analysis of new data concerning the sex of children born to the survivors of the atomic bombings of Hiroshima and Nagasaki, together with a reanalysis of the data previously presented by Neel and Schull (9), reveals significant changes in the sex ratio of these children, changes in the direction to be expected if exposure had resulted in the induction of sex-linked lethal mutations (16).

Incidence of sex chromatin in Gallus domesticus.
The presence of so-called sex chromatin has been demonstrated in the interphase nuclei of the cells of the domestic chicken (Gallus domesticus). Definite sex dimorphism was observed for the incidence of this nuclear component; the frequency of its occurrence in females was at least ten times that of its occurrence in the males, ranging from 22 percent in the duodenal muscle cells to 52 percent in the epidermal cells of a growing feather.

Transfer of the "sexratio" factor in Drosophila willistoni by ingestion.
Thirty-nine females from a normal strain of Drosophila willistoni were kept in bottles containing a drop of a supernatant of a macerate of "sex-ratio" females of the same species. Two of these females acquired the "sex-ratio" condition and transmitted it to their progenies.
