In both cases the principal stages between the pachytene nuclei (A and H) and the formation of the definitive bivalents (G and N) are shown. a priori improbable that a fully developed germinal vesicle stage should be a normal occurrence in spermatogenesis, where the duration of the growth period is comparatively short, and there is little or no deposition of reserve food material. Nevertheless, stages obviously corresponding with the germinal vesicle occur in the male meiotic phases of some animals. There is often F.
