The sex ratio was studied in the offspring of three White Leghorn cocks irradiated locally with a gonad dose of 100 r and of 35 non-irradiated hens of the same breed. It was assumed that irradiation of the cocks would result in a deficit of heterogametic offspring, i.e. of females in the case of birds. The sex ratio in the experimental group (2511 chicks, sex determined post mortem on the first day after hatching) was 0.494 and in the control material (18806 chicks) 0.505. The anticipated increase in the sex ratio after the given radiation dose did not occur. The non significant decrease in the sex ratio is evidently due to other factors and not to irradiation. (auth)
