| Haplogroup S (B254) | |
|---|---|
| Possible place of origin | Possibly Oceania |
| Ancestor | K2b1 |
| Descendants | S1 (B255); S2 P378 |
| Defining mutations | B254, Z33355 |
Haplogroup S also known as S-B254 is a human Y-DNA haplogroup, defined by the SNPs B254 and Z33355.[1] Until 2016, it was known as Haplogroup S1.
S-M254 is the most common haplogroup among males in the Papua New Guinea Highlands. It is also relatively common in some parts of Oceania, Wallacea and among indigenous Australians.[citation needed ]
In a major correction to the phylogenetic tree during 2016, Haplogroup S-M230 was "demoted" from the position of basal clade S*, becoming S1a1b, while S-B254 was "promoted" in its place to the level of S*.[citation needed ]
It has two primary subclades: S1 (B255) and S2 (P378).[1] The existence of a third subclade, defined by the SNP, P336 has not been confirmed.
Prevalence
[edit ]In a study conducted among ~300 individuals who had ancestry in the Papua New Guinea Highlands, 66 of them had ancestry under S-B254.[2]
