Haplogroup CF, also known as CF-P143 and CT(xDE), is a human Y-chromosome DNA haplogroup. CF is defined by the SNP P143, and its existence and distribution are inferred from the fact that haplogroups descended from CF include most human male lineages in Eurasia, Oceania, and The Americas. CF descends from CT (CT-M168), and is the sibling of DE. CF has two basal branches, Haplogroup C and Haplogroup F.[2]

Migration of Haplogroup C.
The geographical development and distribution of Haplogroup F.
There are, as yet, no confirmed cases of living individuals or human remains belonging to the basal, undivergent haplogroup CF*. In the year 2017, C-M217 (C2) & C-M130 were reported among males belonging to the Shan peoples, who are concentrated in central-east Burma (as well as neighboring parts of China, Laos and Thailand).[3] However, the researchers concerned (Brunelli et al.) did not rule out all other subclades of CF, such as haplogroup F, in these particular cases.[citation needed] (In haplogroup F2 has previously been identified in the same geographical region.[4])

^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.)
