廣西茶洞話群體與仫佬族群體的父系和母系遺傳關(guān)系研究
[Abstract]:Background and purpose of the study: About 20,000 people in the northeast of Guangxi, Guangxi, use a new language that is different from that of the surrounding people, and the other ethnic groups in the local area are called "trunk>" tea-hole " un The study of the linguists is that the tea-cave dialect belongs to the Han-Tibetan-Dong-speaking-Dong-water-style branch, and it is very important for both the Chinese and the Chinese. Similar. At present, the user of the tea cave is more recognized as the Han and the minority is Zhuang, but the group does not recognize the family, and according to the inscription, the records of the genealogy of the family have asked the local government many times to identify the "tea-hole" group as the Group of Maonan, so far It is concluded that, to date, there is no clear conclusion on the family of the tea-hole group, and the research is limited to the description of the language and the historical materials and the lack of genetics. The purpose of this paper is to study the genetic structure of the parent and maternal inheritance of the group of tea and the family of the family and to study the genetic origin of these two groups and their inheritance with the surrounding Dong-water population by using the related methods of molecular genetics. The relationship between the origin and the migration of the group of tea and the people of the family. Evidence. Materials and Methods: The non-independent male individuals who use the tea-hole in Lucheng and Lingui of Guangxi are selected as the research object, and the three generations of them can be traced back to their families. The genetic marker system of the Y chromosome and the mitochondria is used for detecting the 17 Y-STR loci by detecting 17 Y-STR loci according to the specific single-group system in East Asia. 0 Y-SNPs. The mitochondrial hypervariable I region and the 22 coding regions SNPs were used to study the genetic characteristics of the parent and female lines of the tea cave and the family of the family, and the main components, the network structure, the multi-dimensional scale and the heritability of the other aquatic plants around the two peoples and the periphery were studied. Statistical analysis of distance and so on to determine the relationship between the two. transmission relation The results showed that the highest allele frequency of the 17 Y-STR loci was DYS391 * 10, the frequency was 80.95%, the highest value of the gene diversity GD was DYS385a/ b (0.9571), the lowest was DYS385a/ b (0.3381), the haplotype diversity HD value was 0.9952, and the high-frequency single group of Y chromosome C-M130 (23.8%), O2 *-P31 (19%) and 02a1 *-M95 (19%). The highest frequency in the Y-STR is DYS438 * 10 (80.39%), the highest GD value is DYS385a/ b (0.880), the lowest is DYS438 (0.3216), the haplotype diversity HD value is 0.9953, and the high-frequency haplotype of the Y chromosome is O1a1-P203 (27.5%). , O2al *-M95 (27.5%). The network structure of the *-M95 shows the tea-tunnel group, the Khmer and the South. The genetic structure of mitochondrial HVS-I was found to be 176 subbase mutations at 48, and the hot spots were 16223,16189 and 16362. The genetic diversity h value was 0.9853 and the coupling probability P was 0.0344. The main mitochondrial haplogroups were B5a. M7b, N9a, R9b1, M7, D5 and F3a. The genetic structure of the matrilineal system of the family of HVS-I: at 76,372 base mutations at the HVS-I, the hot spot mutation sites were 16223,16189 and 16362, forming 72 single-fold type, the coupling probability P value was 0.0177, the gene diversity h value was 0.9930, the main mitochondrial haplogroups were F1 A, M *, B4a, B5a, N9a, M7b *, and M7b1. The genetic relationship between the tea-hole and the family of the family: the major mitochondrial haplogroups of the southern group are present in the tea-and-tunnel-group and the population of the family In case of more than 60%, there is a certain proportion of the characteristics of the Miao nationality and the Chinese Tibetan language group; the main component scatter diagram and the network structure diagram show the two groups and the group of the Han people genetic distance The genetic relationship between the group of tea cave and the family of the family of the family is more than that of the southern group. Conclusion:1. The 17 Y-STR loci and the mtDNA HVS of the group of the tea-hole and the family of the family. -I have a rich genetic polymorphism, which can be applied to individual identification, paternity test, population genetics and so on. The genetic aspect of the present invention is characterized by the typical group of the South China and the South of East Asia, and there is a certain gene exchange with the local Han people. 3. The group of the tea-hole and the family of the people of the Han nationality are mainly from the population of the Bai-Yue, which is composed of the surrounding residents and the people of the Dong-water.
