Haplogroup B (M60) is a human Y-chromosome DNA haplogroup common to paternal lineages in Africa. It is a primary branch of the haplogroup BT.
B (M60) is common in parts of Africa, especially the tropical forests of West-Central Africa. It was the ancestral haplogroup of not only modern Pygmies like the Baka and Mbuti, but also Hadzabe from Tanzania, who often have been considered, in large part because of some typological features of their language, to be a remnant of Khoisan people in East Africa.
According to one study of the Y-DNA of populations in Sudan, haplogroup B-M60 is found in approximately 30% (16/53) of Southern Sudanese, 16% (5/32) of local Hausa people, 14% (4/28) of the Nuba of central Sudan, 3.7% (8/216) of Northern Sudanese (but only among Copts and Nubians), and 2.2% (2/90) of Western Sudanese. [7] According to another study, haplogroup B is found in approximately 15% of Sudanese males, including 12.5% (5/40) B2a1a1a1 (M109/M152) and 2.5% (1/40) B-M60(xM146, M150, M112). [9]
In Madagascar, haplogroup B-M60 has been found in approximately 9% of Malagasy males, including 6% (2/35) B-M60(xB2b-50f2(P)) and 3% (1/35) B2b-50f2(P). [14]
Family Tree DNA shows a significant number of persons of Haplogroup B-M60 (B-M181) claiming origins from the Arabian Peninsula (dominantly Saudi Arabia, but also in Kuwait, Bahrain, Yemen, Qatar, Iraq, United Arab Emirates, and Oman). [15] Sampling bias does not allow for meaningful percentages, but the presence of the haplogroup is solidly attested.

Prior to 2002, there were in academic literature at least seven naming systems for the Y-Chromosome Phylogenetic tree. This led to considerable confusion. In 2002, the major research groups came together and formed the Y-Chromosome Consortium (YCC). They published a joint paper that created a single new tree that all agreed to use. Later, a group of citizen scientists with an interest in population genetics and genetic genealogy formed a working group to create an amateur tree aiming at being above all timely. The table below brings together all of these works at the point of the landmark 2002 YCC Tree. This allows a researcher reviewing older published literature to quickly move between nomenclatures.

The following research teams per their publications were represented in the creation of the YCC Tree.
The phylogenetic tree of haplogroup B subclades is based on the YCC 2008 tree [24] and subsequent published research.
In human genetics, the Y-chromosomal most recent common ancestor is the patrilineal most recent common ancestor (MRCA) from whom all currently living humans are descended. He is the most recent male from whom all living humans are descended through an unbroken line of their male ancestors. The term Y-MRCA reflects the fact that the Y chromosomes of all currently living human males are directly derived from the Y chromosome of this remote ancestor. The analogous concept of the matrilineal most recent common ancestor is known as "Mitochondrial Eve", the most recent woman from whom all living humans are descended matrilineally. As with "Mitochondrial Eve", the title of "Y-chromosomal Adam" is not permanently fixed to a single individual, but can advance over the course of human history as paternal lineages become extinct.
E-M215 or E1b1b, formerly known as E3b, is a major human Y-chromosome DNA haplogroup. E-M215 has two basal branches, E-M35 and E-M281. E-M35 is primarily distributed in North Africa and the Horn of Africa, and occurs at moderate frequencies in the Middle East, Europe, and Southern Africa. E-M281 occurs at a low frequency in Ethiopia.
Haplogroup A is a human Y-chromosome DNA haplogroup, which includes all living human Y chromosomes. Bearers of extant sub-clades of haplogroup A are almost exclusively found in Africa, in contrast with haplogroup BT, bearers of which participated in the Out of Africa migration of early modern humans. The known branches of haplogroup A are A00, A0, A1a, and A1b1; these branches are only very distantly related, and are not more closely related to each other than they are to haplogroup BT.
Haplogroup C is a major Y-chromosome haplogroup, defined by UEPs M130/RPS4Y711, P184, P255, and P260, which are all SNP mutations. It is one of two primary branches of Haplogroup CF alongside Haplogroup F. Haplogroup C is found in ancient populations on every continent except Africa and is the predominant Y-DNA haplogroup among males belonging to many peoples indigenous to East Asia, Central Asia, Siberia, North America and Australia as well as a some populations in Europe, the Levant, and later Japan.
Haplogroup D1 or D-M174 is a subclade of haplogroup D-CTS3946. This male haplogroup is found primarily in East Asia, Magar-ethnic Nepal and the Andaman Islands. It is also found regularly with lower frequency in Central Asia, Siberia and Mainland Southeast Asia, and, more rarely, in Europe and the Middle East.
Haplogroup E-M96 is a human Y-chromosome DNA haplogroup. It is one of the two main branches of the older and ancestral haplogroup DE, the other main branch being haplogroup D. The E-M96 clade is divided into two main subclades: the more common E-P147, and the less common E-M75.
Haplogroup E-V38, also known as E1b1a-V38, is a major human Y-chromosome DNA haplogroup. E-V38 is primarily distributed in Africa. E-V38 has two basal branches, E-M329 and E-M2. E-M329 is a subclade mostly found in East Africa. E-M2 is the predominant subclade in West Africa, Central Africa, Southern Africa, and the region of African Great Lakes; it also occurs at moderate frequencies in North Africa, West Asia, and Southern Europe.
Haplogroup L-M20 is a human Y-DNA haplogroup, which is defined by SNPs M11, M20, M61 and M185. As a secondary descendant of haplogroup K and a primary branch of haplogroup LT, haplogroup L currently has the alternative phylogenetic name of K1a, and is a sibling of haplogroup T.
Haplogroup P also known as P-F5850 or K2b2 is a Y-chromosome DNA haplogroup in human genetics. P-F5850 is a branch of K2b, which is a branch of Haplogroup K2 (K-M526).
In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by mutations in the non-recombining portions of DNA from the male-specific Y chromosome. Many people within a haplogroup share similar numbers of short tandem repeats (STRs) and types of mutations called single-nucleotide polymorphisms (SNPs).
Haplogroup DE is a human Y-chromosome DNA haplogroup. It is defined by the single nucleotide polymorphism (SNP) mutations, or UEPs, M1(YAP), M145(P205), M203, P144, P153, P165, P167, P183. DE is unique because it is distributed in several geographically distinct clusters. An immediate subclade, haplogroup D, is mainly found in East Asia, parts of Central Asia, and the Andaman Islands, but also sporadically in West Africa and West Asia. The other immediate subclade, haplogroup E, is common in Africa, and to a lesser extent the Middle East and southern Europe.
Haplogroup BT M91, also known as Haplogroup A1b2, is a Y-chromosome haplogroup. BT is a subclade of haplogroup A1b (P108) and a sibling of the haplogroup A1b1 (L419/PF712).
The various ethnolinguistic groups found in the Caucasus, Central Asia, Europe, the Middle East, North Africa and/or South Asia demonstrate differing rates of particular Y-DNA haplogroups.
Haplogroup R1b (R-M343), previously known as Hg1 and Eu18, is a human Y-chromosome haplogroup.
Haplogroup E-M75 is a human Y-chromosome DNA haplogroup. Along with haplogroup E-P147, it is one of the two main branches of the older haplogroup E-M96.
Haplogroup E-V68, also known as E1b1b1a, is a major human Y-chromosome DNA haplogroup found in North Africa, the Horn of Africa, Western Asia and Europe. It is a subclade of the larger and older haplogroup, known as E1b1b or E-M215. The E1b1b1a lineage is identified by the presence of a single nucleotide polymorphism (SNP) mutation on the Y chromosome, which is known as V68. It is a subject of discussion and study in genetics as well as genetic genealogy, archaeology, and historical linguistics.
Haplogroup E-P2, also known as E1b1, is a human Y-chromosome DNA haplogroup. E-P2 has two basal branches, E-V38 and E-M215. E-P2 had an ancient presence in East Africa and the Levant; presently, it is primarily distributed in Africa where it may have originated, and occurs at lower frequencies in the Middle East and Europe.
The proportions of various human Y-DNA haplogroups vary significantly from one ethnic or language group to another in Africa.
Haplogroup A-L1085, also known as haplogroup A0-T is a human Y-DNA haplogroup. It is part of the paternal lineage of almost all humans alive today. The SNP L1085 has played two roles in population genetics: firstly, most Y-DNA haplogroups have diverged from it and; secondly, it defines the undiverged basal clade A-L1085*.
Haplogroup E-M2, also known as E1b1a1-M2, is a human Y-chromosome DNA haplogroup. E-M2 is primarily distributed within Africa followed by West Asia. More specifically, E-M2 is the predominant subclade in West Africa, Central Africa, Southern Africa, and the region of the African Great Lakes; it also occurs at moderate frequencies in North Africa, and the Middle East. E-M2 has several subclades, but many of these subhaplogroups are included in either E-L485 or E-U175. E-M2 is especially common among indigenous Africans who speak Niger-Congo languages, and was spread to Southern Africa and East Africa through the Bantu expansion.
