【摘要】 本研究通过外周血淋巴细胞培养的方法,对二只金丝猴的染色体组型和染色体带型进行了分析。现已确证,金丝猴的2倍体细胞的染色体数目为2n=44。雄性为XY,雌性为XX。在染色体组型分析中,测量和计算了每一染色体的相对长度,臂比和着丝点指数。染色体和染色单体的“自发”畸变率分别为0.67％和2％。从姬姆萨(Giemsa)氏带型分析表明,每一对同源染色体都有自己的特殊带型,因此所有的染色体都能予以识别,并能准确无误的配对。更多还原

【Abstract】 In this study,the karyotype and Giemsa banding pattern of the chromosomes of cultured peripheral blood lymphocytes in R.r.roxellanae were investigated.The chromosome number of this species is 44 in both sexes.In R.r.raxellanae,as in other monkeys,sex is determined by specific sex chromosomes,i.e.the male is XY and the female is XX.The 21 pairs of autosomes consist of 7 pairs of metacentric chromosomes,13 pairs of submetacentric ones,1 pair of acrocentric ones.Chromosome measurements were made from highly enlarged photographic prints.Table II lists the results obtained including the relative length,arm ratio and centromere index of each chromosome.Both chromosomal and the chromatid aberrations were observed.They were 0.67% and 2%,respectively.Finally,Giemsa banding pattern analysis of chromosomes of R.r.roxellanae were carried out.The results show that each homologous pair has its own special banding pattern,so that each of them is easily recognizable.Idiograms of chromosome complements with the Giemsa banding pattern were constructed.更多还原
