核仁组成区（NORs）和C-带多态性的存在下，松鼠猴三个亚种，松鼠猴，松鼠猴，S.boliviensis boliviensis，和5. boliviensis peruviensis进行了检查。在这三组中还检测了15和16号染色体的臂间倒位。15号染色体为近端着丝粒染色体，玻利维亚和秘鲁链球菌为近中部着丝粒染色体。16号染色体在松鼠和玻利维亚链球菌中为近端着丝粒染色体，而在秘鲁链球菌中为亚中部着丝粒染色体。卡方分析表明，在3组人群中，5号和14号染色体上C带多态性的分布有显著差异，而2号染色体上NOR多态性的分布无显著差异。14号染色体的NOR多态性和间质C-带多态性在三个群体中均被发现，5号染色体的C-带多态性仅在松鼠中被发现。对12个家系进行了调查。系谱分析结果与各多态性的共显性遗传一致。松鼠猴的这些细胞遗传学研究结果与遗传管理和研究方案有关。
The presence of nucleolar organizer regions (NORs) and C-band polymorphisms has been examined in three subspecies of squirrel monkeys,Saimiri sciureus sciureus, S.boliviensis boliviensis,and 5.boliviensis peruviensis. Pericentric inversions in chromosomes 15 and 16 were also examined in the three groups. Chromosome 15 was acrocentric inS.s.sciureusand sub-metacentric inS.b.boliviensisandS.b.peruviensis. Chromosome 16 was acrocentric inS.s.sciureusandS.b.boliviensiswhile being submetacentric inS.b.peruviensis. There was a significant difference in the distribution of the C-band polymorphisms on chro mosomes 5 and 14 in the three groups, as determined by Chi-square analysis, while no difference was observed in the distribution of the NOR polymorphism on chromosome 2. The NOR polymorphism and the interstitial C-band polymorphism of chromosome 14 were found in all three groups; the C-band polymorphism of chromosome 5 was found only inS.s.sciureus. Twelve pedigreed families were examined. Pedigree analyses were consistent with codominant inheritance of each polymorphism. The results of these cytogenetic studies in squirrel monkeys are pertinent to genetic management and research protocols.
