As a primary branch of [[haplogroup LT]] (a.k.a. K1), the [[Basal (phylogenetics)|basal]], undivergent haplogroup '''T*''' currently has the alternate [[phylogenetic name]] of '''K1b''' and is a sibling of haplogroup [[Haplogroup L-M20|L*]] (a.k.a. K1a). (Before 2008, haplogroup T and its subclades were known as haplogroup K2.<ref name="Mendez2011">{{cite journal |vauthors=Mendez FL, Karafet TM, Krahn T, Ostrer H, Soodyall H, Hammer MF |title=Increased resolution of Y chromosome haplogroup T defines relationships among populations of the Near East, Europe, and Africa |journal=Human Biology |volume=83 |issue=1 |pages=39–53 |year=2011 |pmid=21453003 |doi=10.3378/027.083.0103|s2cid=207611348 }}</ref> The name K2 has since been reassigned to a primary subclade of haplogroup K.) It has two primary branches: [[Haplogroup T-L206 (Y-DNA)|T1]] (T-L206) and T2 (T-PH110). Most males who now belong to haplogroup T1* carry the subclade T-M70 (T1a), a primary branch of T-M206.
 
Haplogroup T is found at exceptionally high levels amongst the [[Dir (clan)|Dir]] and [[Isaaq]] [[Somali people|Somali]] clans in [[Somaliland]],{{efn| ''[[de facto]]'' state}}<ref name="Hodd22">Michael Hodd, ''East Africa Handbook'', 7th Edition, (Passport Books: 2002), p. 21: "To the north are the countries of the Horn of Africa comprising Somalia, Ethiopia, Eritrea, Djibouti, and Somaliland."</ref> [[Djibouti]], and [[Ethiopia]].<ref name="Iacovacci162">Giuseppe Iacovacci ''et al.'', "Forensic data and microvariant sequence characterization of 27 Y-STR loci analyzed in four Eastern African countries," ''^Forensic Science International: Genetics'', 2016</ref><ref name="Iacovacci16222">{{cite web | url=https://www.yfull.com/tree/T-Y16897/ | title=T-Y16897 YTree }}</ref> it is also found at relatively high levels in specific populations in other parts of the world. These include [[Yerukala people|Kurru]], [[Bauris]] and [[Lodha people|Lodha]] in South Asia; among [[Toubou people|Toubou]] in Chad; and in a significant minority of [[Rajus]] and [[Mahli (tribe)|Mahli]] in South Asia; general Somalis, [[Upper Egypt|southern Egyptians]] and [[Fula people|Fula]] (Fulbe) in north [[Cameroon]]; people from the [[Chios|Chian]], [[L'Aquila|Aquilani]], [[Sciacca|Saccensi]], [[Ibiza]]n (Eivissenc) and [[Miranda do Douro|Mirandese]] regions in Europe; [[Zoroastrian]]s, [[Bakhtiari people|Bakhtiaris]] in the Middle East, and [[Nenets people|Nenets]] and [[Kazakhs]] (especially [[Momyn]]sMomyns and [[Argyn]]s) in Siberia/Central Asia. {{citation needed|date=May 2015}}
