Y-chromosomal DNA haplogroups and their implications for the dual origins of the Koreans

Han-Jun Jin et al.

We have analyzed eight Y-chromosomal binary markers (YAP, RPS4Y711, M9, M175, LINE1, SRY+465, 47z, and M95) and three Y-STR markers (DYS390, DYS391, and DYS393) in 738 males from 11 ethnic groups in east Asia in order to study the male lineage history of Korea. Haplogroup DE-YAP was found at a high frequency only in Japan but was also present at low frequencies in northeast Asia, including 2.5% in Korea, suggesting a northern origin for these chromosomes. Haplogroup C-RPS4Y711 was present in Korea and Manchuria at moderate frequencies: higher than in populations from southeast Asia, but lower than those in the northeast, which may imply a northern Asian expansion of these lineages, perhaps from Mongolia or Siberia. The major Y-chromosomal expansions in east Asia were those of haplogroup O-M175 (and its sublineages). This haplogroup is likely to have originated in southern east Asia and subsequently expanded to all of east Asia. The moderate frequency of one sublineage in the Koreans, haplogroup O-LINE1 (12.5%), could be a result of interaction with Chinese populations. The age of another sublineage, haplogroup O-SRY+465, and Y-STR haplotype diversity provide evidence for relatively recent male migration, originally from China, through Korea into Japan. In conclusion, the distribution pattern

I've sent in my DNA samples to National Geographic and they'll be sending me results soon. I wonder if I'll match up with what you posted.

Haplotype O is a very Han Chinese Y marker. It shows that the 3 East Asian ethnicities share 'a lot' in common, but the bad blood is always with closest neighbors and relatives. If these DNA studies are more readily well-known, people will have a lot to reflect. If our blood and genes are the same, why was our past so unfamilial-like?

no offense to anyone but some of our genes(east asians or otherwise) didn't come from mutually consenting adults. I'm sure rape, forced marriage, concubines, sexual slavery of women and conquest etc. was common.

For example, during the Hideyoshi invasion of Korea (1592-1598) there were over 150,000 Japanese troops in the first invasion (1592) and then about 130,000 in 1598. During this time there was a lot of raping and pilliaging going on. Even the Ming forces which numbered about 50,000 when they first arrived were no better than the Japanese. The scale of the war's destruction was so great that about third of the native population perished. I speculate that through this war alone Japanese and Chinese genes added to the Korean gene pool. I'm sure everyone here knows this but war, conquest and occupation is one way to insure the conquerors' genes on the native population.

Of course, I'm sure gene migration all changes with the 20th century and a shrinking world.


I also have to ask out of my own ignorance about genetics, that when you say something like"2.5 %....suggesting a northeastern origin" what do you mean by origin? How would we know if those shared genes didn't come into that gene pool in relatively *recent* history and through violence like in the example I stated ? Please inform because perhaps some of my assumptions needs to be cleared up.
