In this study the yield of the proliferation of the differentiating spermatogonia into spermatocytes was determined in five Chinese hamsters. Large differences of up to a factor 2 were found between the numbers of A1 spermatogonia in the various animals. However, the numbers of leptotene spermatocyt
The sequence of centromere separation in spermatogonial chromosomes of untreated and cyclophosphamide-treated Chinese hamsters is described. Centromeres of chromosome 1 and 2 separated much earlier than all other chromosomes, especially 6-8. Cyclophosphamide significantly inhibits the centromere sep
