Abstract
We analyzed seven Y chromosome binary markers (YAP, RPS4Y711, M9, M175, LINE1, SRY+465 and 47z) in samples from a total of 254 males from Koreans and two Mongolian ethnic groups (Buryat and Khalkh) to study the genetic relationship among these populations. We found eight distinct Y haplogroups constructed from the seven binary markers. Haplogroup DE‐YAP was present at extremely low frequencies (∼2%) in the Korean and Mongolian populations. This result is consistent with earlier reports that showed the YAP+ chromosomes to be highly polymorphic only in populations from Japan and Tibet in east Asia. The observed high frequency of haplogroup C‐RPS4Y711 in the Mongolian populations (∼40%) is concordant with recent findings, showing that the RPS4Y711‐T chromosomes were distributed at high frequencies in Siberian and Mongolian populations compared with most other populations from east Asia. Thus, the relatively moderate frequency of haplogroup C‐RPS4Y711 in Koreans (∼15%) can be seen as genetic evidence for prob...
