内蒙古三个民族舌运动类型的遗传学研究   总被引:28,自引:3,他引:25  
调查了内蒙古汉、蒙古、回族舌运动类型(卷舌、翻舌、叠舌、三叶舌与尖舌),共716例。研究结果显示:各种舌运动类型出现率性别间均无显著性差异;卷舌基因分别与叠、翻、尖、三叶舌基因间存在着互相作用关系,卷舌基因对叠舌基因是隐性上位基因,对翻舌、尖舌、三叶舌基因是修饰基因;内蒙古3个民族间卷、叠、尖舌出现率接近。本文首次调查并研究了尖舌性状。尖舌在过去国内外文献中未见报道。 Abstract:The tongue moving types(including tongue rolling,tongue twisting,tongue folding,clover-leaf tongue and pointed tongue)of 716 cases of Han,Mongol and Hui nationalities in Inner Mongolia were investigated.The results showed that no difference in the frequencies of various tongue moving types between male and female and that the frequencies of rolling,folding and pointed tongue were close to each other among the three nationalities of Inner Mongolia.However,some interactions between genes were revealed,that the rolling gene is a recessive epistatic gene to folding gene and a modifier gene to twisting,pointed and clover-leaf gene respectively.The research on pointed tongue in this paper has never been reported in China and abroad.  相似文献

本研究以柴达木山羊、柴达木绒山羊和辽宁绒山羊三个群体共147只山羊为材料,利用聚丙烯酰胺凝胶电泳(PAGE)技术检测了5种血液蛋白质(酶)基因座的遗传多态性,并进行了结构基因遗传共适应的研究,结果发现:45个基因座组合中有10个基因座组合处于遗传不平衡状态,并且这些遗传不平衡皆单纯由遗传共适应差异造成;除辽宁绒山羊Tf-PA-3组合的遗传不平衡包含非等位基因间的遗传共适应差异外,其他基因座组合的遗传不平衡皆由等位基因间的共适应差异,即单基因座的遗传不平衡造成;LAP-EsD组合的共适应差异在群体间有遗传传递现象。 Abstract:With the technology of PAGE,the genetic polymorphism of blood protein and enzyme was investigated,and genetic co-adaptability among structural genes was studied in three goat populations(147 goats) including Chaidamu goat(CS),Chaidamu Cashmere goat(CRS) and Liaoning Cashmere goat(LRS) in Qinghai Province,China.The results were showed that the genetic disequilibrium of 10 locus combinations was found among 45 locus combinations in the three goat populations,and these genetic disequilibria were caused only by the difference of genetic co-adaptability among genes,because there didn′t exist the linkage disequilibrium among non-allelic genes.The genetic disequilibrium including the difference of genetic co-adaptability between non-allelic genes was only found at Tf-PA-3 locus combinations in LRS population,the other ones were all caused by the genetic disequilibrium at a single locus.The difference of genetic co-adaptability of LAP-EsD locus combinations could be messaged among different populations.  相似文献

用PCR-RFLP的技术进一步研究了青海藏族HLA-DPB1的多态性。在19个HLA-DPB1 的等位基因中,共检出18个等位基因。其中,*0501的频率最高(AF=38.0%);其次为*0201(AF=20.0%);未检出*1601。在HLA-DPB1各等位基因的分布上,藏族与中国南方汉族、中国北方汉族等无明显差异,而与高加索人及尼格罗人的差异则较为显著。综合隶属于三大人种11个群体中的HLA-DQA1、-DQB1和-DPB1基因座各等位基因的分布频率,用UPGMA方法构建了分子系统树, 实验结果进一步证实汉藏同源说。 Abstract:Following the study of the polymorphism of the HLA-DQA1and -DQB1in Tibetans of Qinghai Province, the polymorphism of the HLA-DPB1was investigated by the same technique―PCR-RFLP. Among the 19 detectable alleles of HLA-DPB1gene, 18 alleles were detected. The allele *0501 was the most frequent one (AF=38.0%); the allele *0201 (AF=20.0%)was the second one; and *1601 was not found by this technique. Compared with that of Southern Han and Northern Han nationality in China, the distribution of the alleles showed little difference; while compared with that of the Caucasoid and Negroid, it showed significant difference. The result of this report confirmed once more that the Tibetan and Han nationalities came from the same ancestors. Based on the allele frequencies of the three loci within HLAclass II region-HLA-DQA1、-DQB1and -DPB1from 11 groups among three main races in the world, a molecular phylogenetic tree was constructed with the method UPGMA.  相似文献

对710名(男328人,女382人)新疆蒙古族进行了糖精和乙酰水杨酸尝味能力的检测分析。结果表明,蒙古人群中的糖精味盲率为4.648%,没有尝味能力的隐性基因频率为0.2156,具有尝味能力的显性基因频率为0.7844,平均尝味阈值为8.009±1.34(0.108mol/L)。乙酰水杨酸的尝味阈值分布出现了非常明显的双峰一谷分布,表明该性状是单基因决定的性状,谷底7号液(3.00×10-4 mol/L)是味盲的界限,味盲的峰值在1号液(1.7×10-2mol/L),尝味者的峰值在11号液(1.25×10-5mol/L),味盲率为90.282%,。经χ2检验,男、女性的味盲率无显著差异(P>0.90),表明决定乙酰水杨酸尝味能力的基因位于常染色体,对该基因的显隐性等特点尚需通过家系分析进行确定。 Abstract:The saccharin and aspirin tasting abilities have been detected and analyzed in 710 individuals (328men,382women)of Xinjiang Mongol.It is showed that the saccharin taste- blindness ratio among Mongolians was 4.648%,frequency of the recessive gene determining taste-blindness and the dominant gene determining taste ability was 0.2156,and 0.7844 respectively,and its mean testable threshold was 8.00±1.34 (0.108mol/L).Distribution of aspirin tasting threshold appeared a distinct curve with double peaks and single bottom,and demonstrated the aspirin tasting ability was a monogenic character.Solution NO.7 (3.00×10-4mol/L) at the bottom in the curve was the boundary of taste-blindness.The peak of taste-blindness was at the solution NO.1 (1.7×10-2mol/L),and the peak of tasters was at the solution NO.11 (1.25×10-5mol/L),The ratio of aspirin taste-blindness was 90.28%.The χ2 test has been used to evaluate the statistical difference in aspirin taste-blindness ratio between male and female,the result showed that there was no significant difference (P>0.90),and the gene determining for aspirin tasting ability located on autosomes.  相似文献

Five characteristics (hair forms,nasal profile,nostril forms,mongoloid fold and upper eyelid fold) were respectively investigated in six nationalities,including the Buyi,Miao,Shui,Maonan,Dong,and Han nationalities in Southern Guizhou,China.The gene frequencies of five characteristics in the six nationalities were estimated and compared.The results indicated that:(1) for hair forms and nasal profile,the frequency of the dominant gene was lower than that of their recessive gene,but the opposite was true for nostril forms.(2) Among different nationalities,the difference of gene frequency of the mongoloid fold,nasal profile,hair forms and upper eyelid fold was quite significant,which was followed by that of nostril forms.  相似文献
