Haplogroup Q (mtDNA)
In human mitochondrial genetics, haplogroup Q is a Human mitochondrial DNA haplogroup, human mitochondrial DNA (mtDNA) haplogroup typical for Oceania. It is a subgroup of haplogroup Haplogroup M (mtDNA), M29'Q. Origin Haplogroup Q is a descendant of Haplogroup M (mtDNA), haplogroup M. Distribution Today, mitochondrial DNA Haplogroup Q is found in the southern Pacific rim, Pacific region, especially in New Guinea, MelanesiamtDNA Haplogroup Testing and indigenous Australians. Haplogroup Q is very diverse and frequently occurring among Papuan and Melanesian populations, with an inferred coalescence time of approximately 50,000 years before present. The frequency of this haplogroup among the populations of the islands of Wallacea in eastern Indonesia is quite high, indicating some genetic affinity between the p ...

Human Mitochondrial DNA Haplogroups
In human genetics, a human mitochondrial DNA haplogroup is a haplogroup defined by differences in Human mitochondrial genetics, human mitochondrial DNA. Haplogroups are used to represent the major branch points on the mitochondrial phylogenetic tree. Understanding the evolutionary path of the female lineage has helped population geneticists trace the matrilineality, matrilineal inheritance of modern humans back to human origins in Africa and the subsequent spread around the globe. The letter names of the haplogroups (not just mitochondrial DNA haplogroups) run from A to Z. As haplogroups were named in the order of their discovery, the alphabetical ordering does not have any meaning in terms of actual genetic relationships. The hypothetical woman at the root of all these groups (meaning just the mitochondrial DNA haplogroups) is the matrilineal most recent common ancestor, most recent common ancestor (MRCA) for world population, all currently living humans. She is commonly called ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Indonesians
Indonesians (Indonesian language, Indonesian: ''orang Indonesia'') are citizens or people who are identified with the country of Indonesia, regardless of their ethnic or religious background. There are more than Ethnic groups in Indonesia, 1,300 ethnicities in Indonesia, making it a Multiculturalism, multicultural Archipelago, archipelagic country with a diversity of languages, culture and religious beliefs. The population of Indonesia according to the 2020 national census was 270.2 million. 56% live on the island of Java, the world's most populous island.

Population Genetics
Population genetics is a subfield of genetics that deals with genetic differences within and among populations, and is a part of evolutionary biology. Studies in this branch of biology examine such phenomena as Adaptation (biology), adaptation, speciation, and population stratification, population structure. Population genetics was a vital ingredient in the emergence of the Modern synthesis (20th century), modern evolutionary synthesis. Its primary founders were Sewall Wright, J. B. S. Haldane and Ronald Fisher, who also laid the foundations for the related discipline of quantitative genetics. Traditionally a highly mathematical discipline, modern population genetics encompasses theoretical, laboratory, and field work. Population genetic models are used both for statistical inference from DNA sequence data and for proof/disproof of concept. What sets population genetics apart from newer, more phenotypic approaches to modelling evolution, such as evolutionary game theory and evolu ...

Human Mitochondrial Genetics
Human mitochondrial genetics is the study of the genetics of human mitochondrial DNA (the DNA contained in human mitochondria). The human mitochondrial genome is the entirety of hereditary information contained in human mitochondria. Mitochondria are small structures in cells that generate energy for the cell to use, and are hence referred to as the "powerhouses" of the cell. Mitochondrial DNA (mtDNA) is not transmitted through nuclear DNA (nDNA). In humans, as in most multicellular organisms, mitochondrial DNA is inherited only from the mother's ovum. There are theories, however, that paternal mtDNA transmission in humans can occur under certain circumstances. Mitochondrial inheritance is therefore non-Mendelian, as Mendelian inheritance presumes that half the genetic material of a fertilized egg (zygote) derives from each parent. This allowed the creation of mitochondrial DNA haplogroups to study population genetics. Eighty percent of mitochondrial DNA codes for mitocho ...

Genetic Genealogy
Genetic genealogy is the use of genealogical DNA tests, i.e., DNA profiling and DNA testing, in combination with traditional genealogical methods, to infer genetic relationships between individuals. This application of genetics came to be used by family historians in the 21st century, as DNA tests became affordable. The tests have been promoted by amateur groups, such as Surname DNA project, surname study groups or regional genealogical groups, as well as research projects such as the Genographic Project. about 30 million people had been tested. As the field developed, the aims of practitioners broadened, with many seeking knowledge of their ancestry beyond the recent centuries, for which traditional pedigrees can be constructed. History The investigation of surnames in genetics Genetics is the study of genes, genetic variation, and heredity in organisms.Hartl D, Jones E (2005) It is an important branch in biology because heredity is vital to organisms' evolution. ...

Genealogical DNA Test
A genealogical DNA test is a DNA-based Genetic testing, genetic test used in genetic genealogy that looks at specific locations of a person's genome in order to find or verify ancestral genealogical relationships, or (with lower reliability) to estimate the ethnicity, ethnic mixture of an individual. Since different testing companies use different ethnic reference groups and different matching algorithms, ethnicity estimates for an individual vary between tests, sometimes dramatically. Three principal types of genealogical DNA tests are available, with each looking at a different part of the genome and being useful for different types of genealogical research: Genealogical DNA test#Autosomal DNA (atDNA) testing, autosomal (atDNA), Genealogical DNA test#Mitochondrial DNA (mtDNA) testing, mitochondrial (mtDNA), and Genealogical DNA test#Y-chromosome (Y-DNA) testing, Y-chromosome (Y-DNA). Autosomal tests may result in a large number of DNA matches to both males and females who have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Borneo
Borneo () is the List of islands by area, third-largest island in the world, with an area of , and population of 23,053,723 (2020 national censuses). Situated at the geographic centre of Maritime Southeast Asia, it is one of the Greater Sunda Islands, located north of Java Island, Java, west of Sulawesi, and east of Sumatra. The island is crossed by the equator, which divides it roughly in half. The list of divided islands, island is politically divided among three states. The sovereign state of Brunei in the north makes up 1% of the territory. Approximately 73% of Borneo is Indonesian territory, and in the north, the East Malaysian states of Sabah and Sarawak make up about 26% of the island. The Malaysian federal territory of Labuan is situated on a small island just off the coast of Borneo. Etymology When the sixteenth-century Portuguese explorer Jorge de Menezes made contact with the indigenous people of Borneo, they referred to their island as ''Pulu K'lemantang'', which ...

Balinese People
The Balinese people (, ) are an Austronesian ethnic group native to the Indonesian island of Bali. The Balinese population of 4.2 million (1.7% of Indonesia's population) live mostly on the island of Bali, making up 89% of the island's population. There are also significant populations on the island of Lombok and in the easternmost regions of Java (e.g. the regency of Banyuwangi). The Balinese are distinctive amongst Indonesian ethnic groups for their adherence to Balinese Hinduism rather than Sunni Islam. Origins The Balinese originated from three periods of migration. The first waves of immigrants came from Java and Kalimantan in prehistoric times and were of Proto-Malay stock. The second wave of Balinese came slowly over the years from Java during the Hindu period. The third and final wave came from Java, between the 15th and 16th centuries, about the same time as the conversion to Islam in Java, causing aristocrats and peasants to flee to Bali after the collapse of the Ja ...

Surigaonon People
The Surigaonon people are an ethnolinguistic group who inhabited on the eastern coastal plain of Mindanao, particularly the provinces of Surigao del Norte, Surigao del Sur and Dinagat Islands. They are also present in the provinces of Agusan del Norte, Agusan del Sur, and in Davao Oriental. They are part of the Bisaya people, who constitute the largest Filipino ethnolinguistic group in the country. History Rajah Siawi and Rajah Kulambo, members of the nobility of the Surigaonon and Butuanon people, respectively, were encountered by the Magellan expedition in 1521 on the island of Limasawa (which was a hunting ground for the rulers). Antonio Pigafetta describes them as being tattooed and covered in gold ornaments. Pigafetta also records the name of the Surigao region as "Calagan". Demographics Currently, the Surigaonons number about 1,000,000 (estimates) based on the population of Surigao del Norte, Surigao del Sur and some speakers of Agusan del Norte. Surigaonons are Aus ...

Filipinos
Filipinos () are citizens or people identified with the country of the Philippines. Filipinos come from various Austronesian peoples, all typically speaking Filipino language, Filipino, Philippine English, English, or other Philippine languages. Despite formerly being subject to Spanish Philippines, Spanish administration, less than 1% of Filipinos are fluent in Spanish language, Spanish. Currently, there are more than 185 Ethnic groups in the Philippines, ethnolinguistic groups in the Philippines each with its own Languages of the Philippines, language, identity, culture, tradition, and history. Names The name ''Filipino'', as a demonym, was derived from the term , the name given to the archipelago in 1543 by the Spaniards, Spanish explorer and Order of Preachers, Dominican priest Ruy López de Villalobos, in honor of Philip II of Spain. During the History of the Philippines (1521–1898), Spanish period, natives of the Philippine islands were usually known in the ...

Haplogroup M (mtDNA)
Haplogroup M is a human mitochondrial DNA (mtDNA) haplogroup. An enormous haplogroup spanning all the continents, the macro-haplogroup M, like its sibling the macro-haplogroup N, is a descendant of the haplogroup L3. All mtDNA haplogroups considered native outside of Africa are descendants of either haplogroup M or its sibling haplogroup N. Haplogroup M is relatively young, having a younger most recent common ancestor date than some subclades of haplogroup N such as haplogroup R. Origins There is a debate concerning the geographical origins of Haplogroup M and its sibling haplogroup N. Both lineages are thought to have been the main surviving lineages involved in the out of Africa migration (or migrations) because all indigenous lineages found outside Africa belong to haplogroup M or haplogroup N. Scientists are unsure whether the mutations that define haplogroups M and N occurred in Africa before the exit from Africa or in Asia after the exit from Africa. Determining th ...
