【摘要】 本研究以全血培养的方法,对恒河猴、熊猴、豚尾猴和短尾猴进行了核型比较研究。结果表明,这四种猴子不仅具有相同的染色体数目(2n=42)和形态,而且G—带和C—带带型也非常一致。因此作者认为,这四种猴子的亲缘关系是十分接近的。更多还原

【Abstract】 Karyotypical and banding pattern studies in the four species of monkeys belonging to genus Macaco have been investigated comparatively by a modified microculture method of peripheral blood cells and other related chromosome technique. In all four species, they have not only the same chromosome number of 2n = 42, but also identical distribution of G-and C-bands. By measuring of the relative lengths and arm ratio, there also reveals no significant difference in the characteristics of the chromosome complements among the four species. So it shows that the coefficient of relationship among them is very close.更多还原
