title: The effect of cyclophosphamide on the centromere separation sequence in Chinese hamster spermatogonia.
abstract: 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 separation in all chromosome groups but does not alter the sequence of separation.
