Goldschmidt on the gypsy moth and its intersexes, and is most clearly demonstrates in Bridges' studies of different sex types in Drosophila. Discusses sex determination and the role of hormones in sex differentiation in the case of man. Depicts the human sex ratio and the cause of significant deviations in it from normality, and discusses the possibility of controlling sex by separating male and female producing sperm.
