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.

^ Haplogroup A1 is also known as A1'2'3'4.
^ F-Y27277, sometimes known as F2'4, is both the parent clade of F2 and F4 and a child of F-M89.
^ Haplogroup LT (L298/P326) is also known as Haplogroup K1.
^ Between 2002 and 2008, Haplogroup T-M184 was known as "Haplogroup K2". That name has since been re-assigned to K-M526, the sibling of Haplogroup LT.
^ Haplogroup K2b (M1221/P331/PF5911) is also known as Haplogroup MPS.
^ Haplogroup K2b1 (P397/P399) is also known as Haplogroup MS, but has a broader and more complex internal structure.
^ Haplogroup P (P295) is also klnown as K2b2.
^ K-M2313*, which as yet has no phylogenetic name, has been documented in two living individuals, who have ethnic ties to India and South East Asia. In addition, K-Y28299, which appears to be a primary branch of K-M2313, has been found in three living individuals from India.
