Y-chromosome data of a Mongolian (surnamed Yu) in Tongren, Guizhou

In 2019, Zhang Xiuxiu from Guizhou Medical University completed his master's thesis "Investigation of 21 Y-SNP Genetic Polymorphisms of 17 Inherited Minorities in Guizhou and 21 Han Nationalities" on Mongolian (Tie Gaiyu) Y in Tongren District, Guizhou chromosome information. .

1. Object of study

The object of research in this article is “the study of 17 generations of Guizhou Miao, Bui, Tujia, Dong, Yi, Gelao, Shui, Hui, Bai, Zhuang, Yao, Maonan, Mongolia, Mulao, Qiang, Manchuria. , and She ". Genetic analysis of polymorphism 21 Y-SNP (Y-chromosomal single nucleotide polymorphism) in region of Y-chromosome NRY (non-recombinant region of Y-chromosome) 1171 cases of males without a direct relationship between ethnic minorities and populations of Han Chinese by place of residence were conducted to obtain above information on Y-chromosome genetic polymorphism and ethnic group data, calculate genetic distance between groups, construct a phylogenetic tree, and study genetic relationship between 17 ethnic minorities and Han in Guizhou and other ethnic groups, which is source of ethnic groups. confirm existence of molecular biology.”

Among them, Mongols (Guizhou Mongols) mainly reside in Dafang County in Bijie District, Xinan County, and Shiqian County in Tongren District. Household registration information has been restored to Mongolian nationality.

For this part of history of Mongolian nationality, article introduces that “Mongolian nationality belongs to Mongolian language family of Altaic language family. The time when Mongolian people entered Guizhou must be time when Mongolian people with surname Yu entered Guizhou. They claimed to be descendants of Genghis Khan. According to "Family Tree" and a large number of tombstones, it is proved that at end of Ming and beginning of Qing dynasties, Mongols (with surname Yu) moved from Sichuan to Dafang, Qianxi and Tongren in the Bijie district of Guizhou city due to unrest in Sichuan province. /p> Y-chromosome data of a Mongolian (surnamed Yu) in Tongren, Guizhou

Mongolia, Xinjiang Mongolian, and Qinghai Tu (all three speak Mongolian) are selected for comparison in this article.

2. Research results

Paternal types of Guizhou Mongol Y chromosome include.

C-RPS4Y711, C2-M217 (1.5%), C2-M48, C2-M407, D-M145, F-M89, K-M9, NO-M214, O-M175, O1a- M119 ( 45.6%), O1b-P31, O1b-M95 (33.8%), O1b2-SRY465, O2-M122 (1.5%), O2a-M324 , O2a2-P021 (1.5%) , O2a2a1a1a-M159, O2a2a1a2-M7 (1.5%), O2a2b1-M134 (14.7%), O2a2b1a1a-M133.

3. Results of comparison with ancient and modern Mongols

Ancient Mongolian people, data source is "Dynamic 6000-year genetic history of Eastern Steppe of Eurasia". Ancient DNA data of period of medieval Mongol Empire (13th-15th centuries), this data is called "from netizens Yang Guigui's data package, a total of 37 paternal persons.

Modern Sino-Mongolian data, select Mongolian Big Data 1521 in 23MF in this article (this data includes Guizhou Mongolian), Modern Chinese Mongolian, and Mongolian Xinjiang and Qinghai Tu.

In order to make a clearer comparison, Mongolian data from present-day Outer Mongolia were selected, as well as 245 Mongolian data in Genetic Features of Mongolian Ethnic Groups Identified by Y-Chromosomal Analysis.

The largest type of Mongolian in Guizhou is O1a-M119, accounting for 45.6%. During Yuan Dynasty, Mongolian accounted for 0%, in present-day China, Mongolian accounted for 3.02%, and in present-day Outer Mongolia, Mongolian language was 0 0 .

The second largest type of Mongolian in Guizhou is O1b-M95, accounting for 33.8%, accounting for 0 in Yuan Dynasty Mongolian, accounting for 1.4% in Modern Chinese Mongolian, and accounting for 1.4% in Modern Mongolian of Outer Mongolia than 0.

The third largest Mongoloid type in Guizhou is O2a2b1-M134 (M134+, M133-), accounting for 14.7%. There are no data on Mongolian Mongoloids (not available downstream of O3).

A comparison of these three paternal types in different populations is as follows:

Basic patrilineal types of Mongolian people in Guizhou compared to Mongolian people in Xinjiang, Tu people in Qinghai, Mongol Empire in 13th and 15th centuries, modern 23MF Mongolian data, and modern Outer Mongolia data Population unrelated, or in other words, a group Tiegaya in modern Mongolian population should have paternal ancestors of South Chinese Han type of type O1a, O1b1a1a, and not the ancient Mongolian population.
