Of 19,446 turkey embryos and poults examined 50.17% were [male][male]. A heavier mortality among [male] embryos reduced the sex ratio of hatched poults to 49.2% [male][male]. Of 8,548 chic embryos and chicks 49.54% were [male][male]. When combined with other published data for chickens, the sex ratio obtained was 49.19% [male][male] or 0.98% lower than for turkeys. There were more [male][male] than [female][female] in small samples of embryos dead before the last week of incubation. During the last week of incubation more [male] than [female] turkeys died; the reverse was true for chickens. The data available indicate that the secondary sex ratio of the strains of turkeys studied is not significantly influenced by sex-linked genes although they perhaps exert an influence in at least some strains and breeds of chickens.
