Haplogroup S-M230
Haplogroup S-M230, also known as S1a1b (and previously as S* or K2b1a4), is a Y-chromosome DNA haplogroup. It is by far the most numerically significant subclade of Haplogroup S1a (and its sole primary subclade, Haplogroup S-P405).
| Haplogroup S-M230 (S1a1b) | |
|---|---|
| Possible time of origin | 28,000-41,000 years before present (Scheinfeldt 2006) |
| Possible place of origin | New Guinea/Indonesia |
| Ancestor | S1a1 (Z42413) |
| Descendants | S1a1b1 (M254) |
| Defining mutations | M230, P202 |
| Highest frequencies | Ekari 74% (Mona 2007) |
S-M230 is commonly found among populations of the highlands of Papua New Guinea (Kayser 2003). It is also found at lower frequencies in adjacent parts of Indonesia and Melanesia. (Kayser 2003 Cox 2006)
