Haplogroup K or K-M9 is a human Y-chromosome DNA haplogroup. A sublineage of haplogroup IJK, K-M9 and its descendant clades comprise a populous geographically diverse haplogroup. They have long been found in men on every continent other than Antarctica.

The direct descendants of K-M9 are Haplogroup K2 (formerly KxLT; K-M526) and Haplogroup LT (L298 = P326).[1][2]

Origins and distribution[edit]

Y-DNA haplogroup K-M9 is an old lineage that arose approximately 47,000 years ago,[3] probably in South Asia or West Asia.

The basal paragroup K* is exceptionally rare, although it has been reported at low frequencies in various parts of Eurasia, Oceania and Africa.[1][4]

The descendants of haplogroup K2 include:


Haplogroup K-M9 tree [1][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]

LT (K1). Widely distributed at low concentrations. Haplogroup L is found at its highest frequency in Pakistan, western India and among the Balochs of Afghanistan. T is most common among: Wodaabe Fulanis (Sahelian Africans), Somalis, some Middle East,[26] the Aegean Islands and a few populations in India


K2* (M526) has been found in an estimated 27% of indigenous Australians (based on large scale surveys in which 56% of the samples were assumed to be non-indigenous.) [27] Also reported for the remains of Ust'-Ishim man, dating from approximately 45,000 BP and found in Omsk Oblast, Russia.[28]

NO (K2a)

N Found near Arctic Circle, Yakuts, Finno Ugrians (Ancient samples: most remains from the Yangshao, Hongshan, ancient Hungarians, Xiongnu and prehistoric Yakuts; some also in the Xiajiadian mixed between O3)

O Sino-Tibetans + modern Longshan and Daxi and Xiajiadian which was divided between N and O3 (Xiajiadian was mixed others were pure) (O3), Austronesians, Polynesians, Melanesians, Malaygasy and in modern Liangzhu to a very low extent (O1), and Austro-Asiatics (O2) dominant east Asian line (O) note O1 and O2 form a clade against O3 called O1'2


K2b1a (CTS5650/F3744/P405), includes Haplogroup S (M230, P202, P204) a.k.a. K2b1a4 which, according to ISOGG, is: "a major haplogroup in the highlands of mainland Papua New Guinea where it is found at frequencies of around 50% in some populations and is also present at lower frequencies in adjacent islands of Indonesia and Melanesia."[29] The subclade K2b1a1 has been reported at levels of up to 27% among indigenous Australians.[27] Other subclades of K2b1a have been reported in other parts of Oceania and Indonesia;

K2b1b (P336): Alor, Timor and Borneo.

K2b1c (P378): Aeta people of the Philippines.

M (P256, Page93/S322) a.k.a. K2b1d. The most common haplogroup in Papua New Guinea; also found in Australia,[27] and neighbouring parts of Melanesia and Polynesia.

P (K2b2)
P* (K2b2*) 28% of Aeta (Philippines), 10% in Timor

 P1* (M45/PF5962) 22.2–35.4% in TuvansKizhi, and Todjins 

Q (M242) Native Americans and Siberia/Central Asia (Kets, Selkups, Turkmen, Altai, Tuvans, Xirong, Mongolian Altai Kurgans)

R* found only in remains from 24,000 years BP at Mal'ta' in Siberia

R2 found in India, Sri Lanka, North Pakistan isolates

R1a found in Eastern Europe, India, Central Asia (especially Altai populations and Uighurs), and Scandinavia. Ancient samples include 10 out of 11 samples from Xiaohe Tomb complex, Andronovo, Pazyryk, Mongolian Altai Kurgans (R1a/Z93 mixed with Q1a2a1/L54), The Tagar Culture, Karasuk culture, Tashtyk culture, some Corded ware folk

R1b West Europe, Chadic Languages, Armenian Highlands (Found in several Bell Beakers from Germany and in late antique Basques of whom it is still common in as well as 13.3% (4):one P probably R1b2 (V88): of Guanches from the Canary Islands, (reports of King Tut belonging to R1b, by iGENEA belonging to R1b have not been verified.)

K2c (P261). Minor lineage of Bali.

K2d (P402). Minor lineage of Java

K2e (M147). Highly rare lineage; two cases in South Asia.[1]
