Haplogroup S1a is a human Y-DNA haplogroup, defined by SNPs Z41335, Z41336, Z41337, Z41338, Z41339, Z41340, and Z41341.
S1a is found primarily in Melanesia (especially in Papua New Guinea), Micronesia, Maritime Southeast Asia and among indigenous Australians. [1]
As of 2017, it includes an unnamed primary subclade referred to by ISOGG as "S1a~" (P405), [1] [2] [3] (which was previously known as K2b1a). The "~" symbol is ISOGG's way of indicating that an unverified and as-yet unnamed immediate ancestor may exist.
Its secondary subclades include: S1a1 (Z42413), S1a2~ (P79, P307) and S1a3 (P315).
Before 2016, S1a1b (M230, P202, P204) was known as Haplogroup S* (and before that as Haplogroup K5). (In 2016, haplogroup S-B254 was "promoted" to S*, from its previous position of S1.)
The "sibling" clades of S1a include: S1b (B275, Z33756, Z33757, Z33758, Z33759), S1c (Z41926, Z41927, Z41928, Z41929, Z41930) and S1d (SK1806).
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. The haplogroup is also found with moderate to low frequency among many present-day populations of Southeast Asia, South Asia, and Southwest Asia.
Haplogroup K or K-M9 is a human Y-chromosome DNA haplogroup. A sublineage of haplogroup IJK, K-M9 and its descendant clades represent a geographically widespread and diverse haplogroup. The lineages have long been found among males on every continent.
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.
Haplogroup N (M231) is a Y-chromosome DNA haplogroup defined by the presence of the single-nucleotide polymorphism (SNP) marker M231.
Haplogroup P also known as P-P295 and K2b2 is a Y-chromosome DNA haplogroup in human genetics. P-P295 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 NO, also known as NO-M214 and NO1, is a human Y-chromosome DNA haplogroup. NO is the sole confirmed subclade of Haplogroup K2a1 (K-M2313), which is the sole subclade of Haplogroup K2a (K-M2308). NO is the dominant Y-DNA haplogroup in most parts of eastern and northern Eurasia, including East Asia, Siberia and northern Fennoscandia.
Haplogroup O-K18 also known as O-F2320 and Haplogroup O1b1, is a human Y-chromosome DNA haplogroup. Haplogroup O-K18 is a descendant branch of Haplogroup O-P31. Based on its disjunct distribution, O-K18 can be further divided into south subclade O1b1a1-PK4 and north subclade O1b1a2-PAGE59. O-PAGE59 is widely distributed in East Asia, whereas O-PK4 is more frequent in South China and Southeast Asia. O-PK4 is best known for the high frequency of its O-M95 subclade among populations of Southeast Asia and among speakers of Austroasiatic languages in South Asia.
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 Europe.
Haplogroup CT is a human Y chromosome haplogroup, defining one of the major paternal lineages of humanity.
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 S-M230, also known as S1a1b, is a Y-chromosome DNA haplogroup. It is by far the most numerically significant subclade of Haplogroup S1a.
In human population genetics, haplogroups define the major lineages of direct paternal (male) lines back to a shared common ancestor in Africa.
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.
Listed here are notable ethnic groups and native populations from the Oceania and East Indonesia by human Y-chromosome DNA haplogroups based on relevant studies.
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 P1, also known as P-M45 and K2b2a, is a Y-chromosome DNA haplogroup in human genetics. Defined by the SNPs M45 and PF5962, P1 is a primary branch (subclade) of P.
Haplogroup K2a is a human Y-chromosome DNA haplogroup. K2a is a primary subclade of haplogroup K2 (M526), which in turn is a primary descendant of haplogroup K (M9). Its sole primary descendant is haplogroup K-M2313.
