A haplotype is a group of alleles in an organism that are inherited together from a single parent, and a haplogroup is a group of similar haplotypes that share a common ancestor with a single-nucleotide polymorphism mutation. More specifically, a haplotype is a combination of alleles at different chromosomal regions that are closely linked and that tend to be inherited together. As a haplogroup consists of similar haplotypes, it is usually possible to predict a haplogroup from haplotypes. Haplogroups pertain to a single line of descent. As such, membership of a haplogroup, by any individual, relies on a relatively small proportion of the genetic material possessed by that individual.
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 F, also known as F-M89 and previously as Haplogroup FT, is a very common Y-chromosome haplogroup. The clade and its subclades constitute over 90% of paternal lineages outside of Africa.
Haplogroup M, also known as M-P256 and Haplogroup K2b1b is a Y-chromosome DNA haplogroup. M-P256 is a descendant haplogroup of Haplogroup K2b1, and is believed to have first appeared between 32,000 and 47,000 years ago.
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).
Haplogroup K2, also known as K-M526 and formerly known as K(xLT) and MNOPS, is a human Y-DNA haplogroup.
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.
Haplogroup E-P147 is a human Y-chromosome DNA haplogroup. Haplogroup E-P147, along with the less common haplogroup E-M75, is one of the two main branches of the older haplogroup E-M96. The E-P147 clade is commonly observed throughout Africa and is divided into two subclades: the less common, haplogroup E-M132, and the more common, haplogroup E-P177.
Haplogroup E-P177 is a human Y-chromosome DNA haplogroup. E-P177 has two known subclades, which are haplogroup E-P2 and haplogroup E-P75.
In human population genetics, Y-Chromosome haplogroups define the major lineages of direct paternal (male) lines back to a shared common ancestor in Africa. Men in the same haplogroup share a set of differences, or markers, on their Y-Chromosome, which distinguish them from men in other haplogroups. These UEPs, or markers used to define haplogroups, are SNP mutations. Y-Chromosome Haplogroups all form "family trees" or "phylogenies", with both branches or sub-clades diverging from a common haplogroup ancestor, and also with all haplogroups themselves linked into one family tree which traces back ultimately to the most recent shared male line ancestor of all men alive today, called in popular science Y Chromosome Adam.
Haplogroup K2b1, known sometimes as haplogroup MS, is a human Y-DNA haplogroup, defined by SNPs P397 and P399. It has a complex, diverse and not-yet fully understood internal structure; its downstream descendants include the major haplogroups Haplogroup M (P256) and Haplogroup S (M230).
Haplogroup K2b (P331), also known as MPS is a human y-chromosome haplogroup that is thought to be less than 3,000 years younger than K, and less than 10,000 years younger than F, meaning it probably is around 50,000 years old, according to the age estimates of Tatiana Karafet et al. 2014.
Haplogroup S1a is a human Y-DNA haplogroup, defined by SNPs Z41335, Z41336, Z41337, Z41338, Z41339, Z41340, and Z41341.
Haplogroup E-M329, also known as E1b1a2, is a human Y-chromosome DNA haplogroup. E-M329 is mostly found in East Africa.
Haplogroup D, also known as D-CTS3946, is a Y-chromosome haplogroup. Like its relative distant sibling, haplogroup E-M96, D-CTS3946 has the YAP+ unique-event polymorphism, which defines their parent, haplogroup DE. D-CTS3946 has two basal branches, D1 and D2. D1 and D2 are found primarily in East Asia, at low frequency in Central Asia and Southeast Asia, and at very low frequency in Western Africa and Western Asia.
