食蟹猴和熊猴杂种F1的细胞遗传学研究

本工作采用染色体显带、睾丸组织学切片以及低渗铺张－硝酸银染色等方法较为详细地研究了食蟹猴和（Ｍ．ｆａｓｃｉｃｕｌａｒｉｓ）和熊猴（Ｍ．ａｓｓａｍｅｎｓｉｓ）种间杂种Ｆ１体细胞染色体的Ｇ带、Ｃ带、Ａｇ－ＮＯＲ、精母细胞联合复合体的结构、形态和行为以及精子发生。结果表明：（１）杂种亲本的染色体组具有高度的同源性；（２）杂种的精子发生过程完全正常；（３）食蟹猴和熊猴的种间生植屏障可能主要是生态隔离。此外

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 highiy 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.
