Haplogroup C-M8 also known as Haplogroup C1a1 is a Y-chromosome haplogroup. It is one of two branches of Haplogroup C1a, one of the descendants of Haplogroup C-M130.
It has been found in about 6% (2.3% to 16.7%) of modern males sampled in Japan and has been considered to be a Y-DNA haplogroup descended from Jōmon people. [5] [6] Elsewhere, it has been observed among academic studies only in one individual in a sample collected on Jeju Island of South Korea [7] and in commercial testing in one individual who has reported an origin in Liaoning province of China and one individual who has reported an origin in Seoul, South Korea. [8]
The MRCA with its sister haplogroup C-V20 dates back to 40,000 [1] to 50,000 [2] years ago. Diffusion of existing subtypes of C-M8 is estimated to have begun about 12,000 years ago. [3]
C1a1 is found in the Jōmon people and are linked to the Jomon people who came from the south route.
Frequency in samples of Japanese from various regions: [6]
Haplogroup C1a1 (M8) is mostly unique to the Japanese archipelago, and its migration route is enigmatic.
C1a1 is estimated to be one of the common haplogroups among the Jōmon people (about 30% or more), next to D1a2a, D1a1, C2, K, and F. [15]
Jōmon people is the generic name of the indigenous hunter-gatherer population that lived in the Japanese archipelago during the Jōmon period. They were united through a common Jōmon culture, which reached a considerable degree of sedentism and cultural complexity.
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-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 Q or Q-M242 is a Y-chromosome DNA haplogroup. It has one primary subclade, Haplogroup Q1 (L232/S432), which includes numerous subclades that have been sampled and identified in males among modern populations.
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).
In human genetics, Haplogroup O-M119 is a Y-chromosome DNA haplogroup. Haplogroup O-M119 is a descendant branch of haplogroup O-F265 also known as O1a, one of two extant primary subclades of Haplogroup O-M175. The same clade previously has been labeled as O-MSY2.2.
Haplogroup C-M217, also known as C2, is a Y-chromosome DNA haplogroup. It is the most frequently occurring branch of the wider Haplogroup C (M130). It is found mostly in Central Asia, Eastern Siberia and significant frequencies in parts of East Asia and Southeast Asia including some populations in the Caucasus, Middle East, South Asia, East Europe. It is found in a much more widespread area with a low frequency of less than 2%.
In human mitochondrial genetics, Haplogroup G is a human mitochondrial DNA (mtDNA) haplogroup.
Haplogroup CT is a human Y chromosome haplogroup. CT has two basal branches, CF and DE. DE is divided into a predominantly Asia-distributed haplogroup D-CTS3946 and a predominantly Africa-distributed haplogroup E-M96, while CF is divided into an East Asian, Native American, and Oceanian haplogroup C-M130 and haplogroup F-M89, which dominates most non-African populations.
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.
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.
The tables below provide statistics on the human Y-chromosome DNA haplogroups most commonly found among ethnolinguistic groups and populations from East and South-East Asia.
Haplogroup C1 also known as C-F3393, is a major Y-chromosome haplogroup. It is one of two primary branches of the broader Haplogroup C, the other being C2.
In Japanese history, the Jōmon period is the time between c. 14,000 and 300 BC, during which Japan was inhabited by a diverse hunter-gatherer and early agriculturalist population united through a common Jōmon culture, which reached a considerable degree of sedentism and cultural complexity. The name "cord-marked" was first applied by the American zoologist and orientalist Edward S. Morse, who discovered sherds of pottery in 1877 and subsequently translated "straw-rope pattern" into Japanese as Jōmon. The pottery style characteristic of the first phases of Jōmon culture was decorated by impressing cords into the surface of wet clay and is generally accepted to be among the oldest in the world.
Haplogroup C-M48 also known as C2b1a2 is a Y-chromosome DNA haplogroup.
Haplogroup D-M55 (M64.1/Page44.1) also known as Haplogroup D1a2a is a Y-chromosome haplogroup. It is one of two branches of Haplogroup D1a. The other is D1a1, which is found with high frequency in Tibetans and other Tibeto-Burmese populations and geographical close groups. D is also distributed with low to medium frequency in Central Asia, East Asia, and Mainland Southeast Asia.
Haplogroup D-Z27276 also known as Haplogroup D1a1 is a Y-chromosome haplogroup. It is one of two branches of Haplogroup D1, one of the descendants of Haplogroup D. The other is D-M55 which is only found in Japan.
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.
