[Studies of the miotic chromosomes, meiosis and spermatogenesis of a macaque hybrid].
The mitotic and meiotic chromosomes, as well as the spermatogenesis of a male hybrid between Macaca fascicularis and M. assamensis have been studied using chromosome banding, microspreading, and tissue sectioning techniques. The band patterns of the parental chromosome complements are found highly homologous. The observation on meiosis and testis histology indicates that the hybrid should be fertile. It is suggested that the reproductive barrier between M. fascicularis and M. assamensis is not complete and may resulted from ecological isolation. The taxonomic status of M. fascicularis and M. assamensis is discussed also.
