Modern populations with living members of
K2b1 (all subclades), P* (a.k.a. K2b2*; P-P295*) and P2 (K2b2b) appear to be restricted to
Oceania,
South East Asia and
Siberia. Basal, un-mutated P1* (K2b2a*; P-M45*), in modern times, is distributed in isolated pockets, over a relatively wide area that includes
Island South East Asia. Some
Negrito populations of South-East Asia carry next to noteworthy East Asian ancestry, very high levels of K2b at the subclade level. It is carried, for instance, by more than 83% of males among the
Aeta (or Agta) people of the Philippines, in the form of
K2b1 (60%),
P* (P-P295*, a.k.a. K2b2*) and
P2 (P-B253; K2b2b).
K2b1 K2b1 is found in 83% of males of Papua New Guinea, and up to 60% in the
Aeta people of the
Philippines. (The other Y-DNA haplogroups found were: basal K2* [K-M526], C1b2b [M347; previously Haplogroup C4], and basal C* [M130].)
P (K2b2) Apart from the basal paragroup
P* (K2b2), it has only one subclade: P1 (M45), also known as K2b2a – which is also the parent of the major haplogroups Q (K2b2a1) and R (K2b2a2). and 35% among
Nivkh males. Modern South Asian populations also feature P1 at low to moderate frequencies. In South Asia it is most frequent among the Muslims of
Manipur (33%), but this may be due to a very small sample size (nine individuals). Cases of P1 (M45) reported in South Asia may be unresolved cases or R2 or Q. §
These may include members of haplogroup R2. == See also ==
