Haplogroup IJK
Possible time of origin	49,000-59,000 BP^[1]
Possible place of origin	Eurasia
Ancestor	Haplogroup HIJK
Descendants	IJ, K
Defining mutations	L15/S137, L16/S138, L69.1(=G)/S163.1

Haplogroup IJK is a human Y-chromosome DNA haplogroup. IJK is a primary branch of the macrohaplogroup HIJK. Its direct descendants are haplogroup IJ and haplogroup K.^[2]

Distribution and structure[edit]

IJK has not been reported in modern populations or in ancient human remains. Previously basal paragroup HIJK* was reported in a Mesolithic European (Magdalenian), GoyetQ-2, and Upper Paleolithic European (Gravettian), Vestonice16.^[3] Later study in 2023 with high quality sequencing of Magdalenian, GoyetQ-2, Gravettian, Vestonice16 were assigned with Haplogroup I.^[4]

Populations with high proportions of males who belong to descendant major haplogroups of Haplogroup HIJK live across widely dispersed areas and populations. Subclades of IJK are now concentrated in males native to:

Europe (e. g. haplogroups I, J, R and N);
the Caucasus, Near East and North East Africa (e.g. haplogroups J and T);
South Asia (e.g. haplogroups J, L and R);
East Asia，Southeast Asia, Oceania, and the Pacific (e. g. haplogroups K, M, O, P, S)
Northern Eurasia, (e.g. haplogroups N and Q) and;
Native American peoples (e. g. haplogroup Q and R).

Phylogenetic tree[edit]

Haplogroup IJK†

	I1 found mainly in Northern Europe.

	I2found mainly in South-Eastern Europe

	J1 found mainly in the Caucasus and Middle East.

	J2 found mainly in the Caucasus, Western Asia, Near East, Central Asia, South Asia and Southern Europe.

K†

LT†

	L found mainly in Central Asia, South Asia and Western Asia.

	T now concentrated in the West Anatolia, Horn of Africa, the Arabian subcontinent, India and Eurasia.

K2* – the basal subclade is found at significant levels among indigenous Australians. Also found at Mandar and Toba Batak one of the Indigenous Tribe in Sundaland.^[5]

NO* † (found only in the remains of Ust'-Ishim man,<br /> dating from 45,000 BP ^[7]) → NO1 (K2a)

	NO1* †

	N found mainly in Northern Asia and Northern Europe.

	O found mainly in East Asia, Southeast Asia, and Oceania.

K2b†

K2b1*† – subclades of K2b1 include the major haplogroups M and S; these are now found mainly among Papuan peoples, Micronesian peoples, indigenous Australians, and Polynesians

P (K2b2)

	P* rare; found mostly in Island South East Asia, Eastern Siberia and Central Asia

	P1 – the primary subclades are major haplogroups Q and R, which are now numerically dominant in Central Asia, Europe, South Asia, the Middle East and among Native Americans

	P2 extremely rare and found only in the Philippines

K2c – rare lineage, found mainly in males from Bali^[6]

K2d – rare lineage, found mainly in Java

K2e – rare lineage, found only in two living males from South India^[6]

† = A basal haplogroup that has not been documented among living individuals.

(Based on the YCC 2008 tree and subsequent published research.^[8])

^ 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.

^ Haplogroup S, as of 2017, is also known as K2b1a. (Previously the name Haplogroup S was assigned to K2b1a4.)

^ Haplogroup M, as of 2017, is also known as K2b1b. (Previously the name Haplogroup M was assigned to K2b1d.)
