Y-Haplogroup O-F793

All F793 people have the same male ancestor about 2600 to 2700 years ago. He originated in the middle reaches of the Yangtze River. He was one of the super ancestors in Chinese historical period. At present, about 1.20% of the men in China is F793. The distribution is as follows:

Introduction to the upstream ancestors

The number is the estimated age (ybp) to most recent common ancestor by YFULL v8.00.00

• O, M175, 30500 Originated in East Asia, now mainly distributed in East Asia, Southeast Asia and some Pacific islands. It accounts for about 77% of the Chinese male population.
• O2, M122, 28800 Formerly known as O3, accounting for approximately 56% of the Chinese male population.
• O2a, M324, 23600
• O2a1, L127.1, 16500
• O2a1b, IMS-JST002611, 12900 Online information often use the old name O2a1c, O3a1c or simply 002611. It accounts for about 14% of the Chinese male population. 002611 has many branches in only several hundred years after when it is formed, it showing a population expansion trend. And there is a time that there is no known subclades of 002611 branch, so there are many information and discussion based on 002611. This round of population expansion is presumed to be between Late Glacial to Younger Dryas impact hypothesis, when the climatic conditions were greatly improved.
• O2a1b1, F18, 12500
• O2a1b1a, FGC12511
• O2a1b1a1, F117
• O2a1b1a1a, CTS4598
• O2a1b1a1a1, CTS4263, 10100
• O2a1b1a1a1a, F11
• O2a1b1a1a1a1, F325, 9200 One of the five great Neolithic ancestors in China, accounting for about 11% of the Chinese male population. The overall distribution is biased towards eastern China, both north and south. It has a big clustered downstream, and 24 primary branches have been found now, which means that the number of his offspring has erupted in a very short time. Therefore, Fudan University specifically named it as Oγ. Note that the mark SNP of this branch in the past is F11, so F11 in most article actually refers to this branch.
• O2a1b1a1a1a1a, F632, 9200 Oγ1, the common ancestor time is almost same with Oγ, and it has clustered decedent branches. It can be seen as an extension of the Oγ population boom.
• O2a1b1a1a1a1a1, F110, 8100 Has clustered downstream.
• O2a1b1a1a1a1a1a, CTS3663
• O2a1b1a1a1a1a1a1, F17, 5700 Suspected to originate in the middle reaches of the Yangtze River, accounting for 2.19% of the Chinese male population. F17 common ancestor time and origin place fell into Daxi culture. F17’s dependent branches, F377 and Z43876 both divided to new branches in very short time, which presumed that F17’s ethnic group experienced a period of rapid population expansion, or F17 is a noble class of Daxi culture.
• O2a1b1a1a1a1a1a1b, Z43876 It is slightly later than F17 and may belong to the same ethnic group.

The F793 has many primary branches that to be clusters. However, currently there is less information and further exploration is needed.

• O2a1b1a1a1a1a1a1b1a, Y141213 Has a common ancestor that with surename Liu (刘) at about 2150 years ago. It accounts for about 0.35% of the male population in China. It distributed mainly in the northern China, especially in Baoding, Shijiazhuang, commonly around central Hebei Province, with a ratio of about 2.0%, while the population in southern provinces are very small. It showing totally different distribution with other branches of F793. The decedent of Y141213 appears to be a very big cluster, which means that the number of his offspring erupted in a very short time. The currently known decedent branches are MF7453, MF34218, MF30914, MF34504, Z26397, Y53761, Y64367. Here shows the Y141213 population in part of the northern provinces:

• O2a1b1a1a1a1a1a1b1a1, MF7453 It is only one SNP from Y141213 and is a extension of the Y141213 population boom.

  • MF31821/Y151786, Found in Liaoning

• O2a1b1a1a1a1a1a1b1b, Y65006

• O2a1b1a1a1a1a1a1b1b1, A22940 Found in Fujian and Taiwan.

• O2a1b1a1a1a1a1a1b1c, MF30934/Y151758, Jiangxi Lai (赖).

• O2a1b1a1a1a1a1a1b1c1, MF31684/Y151809, Found in Raiatea (belongs to Society Islands), Taiwan.

• O2a1b1a1a1a1a1a1b1d, Y150436, Jiangxi Nie (聂).

  • Y150276, found in Jiangxi, Yunnan.

• O2a1b1a1a1a1a1a1b1e, CTS10514, found in the southern provinces of China.

• O2a1b1a1a1a1a1a1b1f, F931, Hunan&Sichuan Zhu (朱).

• There may have branches with surename Wu, Huang, Nie, Qu and Lao.
