Human Mutation 35 (2): 187–91. doi:10.1002/humu.22468. PMID 24166809. International Society of Genetic Genealogy (ISOGG; 2015), Y-DNA Haplogroup Tree 2015. (Access date: 1 February 2015.) Haplogroup A0-T is also known as A0'1'2'3'4. Haplogroup A1 is also known as A1'2'3'4. Haplogroup LT (L298/P326) is also known as Haplogroup K1. Haplogroup NO (M214) is also known as Haplogroup K2a (although the present Haplogroup K2e was also previously known as "K2a"). Haplogroup K2b (M1221/P331/PF5911) is also known as Haplogroup MPS. Haplogroup K2e (K-M147) was previously known as "Haplogroup X" and "K2a" (but is a sibling subclade of the present K2a, also known as Haplogroup NO). Haplogroup K2b1 (P397/P399) is similiar to the former Haplogroup MS, but has a broader and more complex internal structure. Haplogroup S (S-M230) was previously known as Haplogroup K5.
