GeneTree
GeneTree was a family history website focused on using DNA testing to trace ancestry. A website account was free, and within their account users could order DNA tests, enter results from other testing companies, search the DNA database, create an online family tree, and correspond with family members – including sharing pictures. Genetree.com was closed on January 1, 2013 and its assets were transferred to Ancestry.com. History GeneTree was founded in 1997 by a graduate of Wayne State University’s Center for Molecular Medicine and Genetics, Terrence Carmichael, who earned a master’s degree in molecular biology and genetics in 1995. Genetree did not offer multi-generational genealogy tests initially. Carmichael declared, “Over 95 percent of our first-year business was in paternity testing.” In fall 2001, GeneTree sold its assets to Salt Lake City-based Sorenson Molecular Genealogy Foundation ("SMGF") which originated in 1999. The GeneTree website brought together elem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sorenson Molecular Genealogy Foundation
The Sorenson Molecular Genealogy Foundation (SMGF) was an independent DNA and genealogical research institution with the goal of demonstrating how the peoples of the world are related. SMGF collected DNA samples and genealogical information from individuals across the globe to establish these connections. History SMGF originated in 1999 and was inspired by several conversations between inventor and philanthropist James LeVoy Sorenson and Brigham Young University professor Dr. Scott Woodward. Mr. Sorenson envisioned the development of a genetic-genealogical blueprint of all humankind. This blueprint, as developed by Dr. Woodward, would show how closely humans are related to one another, demonstrating the familial relationships between unique individuals. The collection of DNA samples and associated family pedigrees began in 2000, beginning first with Brigham Young University students, and quickly branching outside of Utah, then to the rest of the world. In 2003, SMGF moved i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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. ...

Ancestry
An ancestor, also known as a forefather, fore-elder, or a forebear, is a parent or ( recursively) the parent of an antecedent (i.e., a grandparent, great-grandparent, great-great-grandparent and so forth). ''Ancestor'' is "any person from whom one is descended. In law, the person from whom an estate has been inherited." Relationship Two individuals have a genetic relationship if one is the ancestor of the other or if they share a common ancestor. In evolutionary theory, species which share an evolutionary ancestor are said to be of common descent. However, this concept of ancestry does not apply to some bacteria and other organisms capable of horizontal gene transfer. Some research suggests that the average person has twice as many female ancestors as male ancestors. This might have been due to the past prevalence of polygynous relations and female hypergamy. Assuming that all of an individual's ancestors are otherwise unrelated to each other, that individual has 2'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Y Chromosome
The Y chromosome is one of two sex chromosomes in therian mammals and other organisms. Along with the X chromosome, it is part of the XY sex-determination system, in which the Y is the sex-determining chromosome because the presence of the Y chromosome causes offspring produced in sexual reproduction to be of male sex. In mammals, the Y chromosome contains the SRY gene, which triggers development of male gonads. The Y chromosome is passed only from male parents to male offspring. Overview Discovery The Y chromosome was identified as a sex-determining chromosome by Nettie Stevens at Bryn Mawr College in 1905 during a study of the mealworm ''Tenebrio molitor''. Edmund Beecher Wilson independently discovered the same mechanisms the same year, working with Hemiptera. Stevens proposed that chromosomes always existed in pairs and that the smaller chromosome (now labelled "Y") was the pair of the X chromosome discovered in 1890 by Hermann Henking. She realized that th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitochondrial DNA
Mitochondrial DNA (mtDNA and mDNA) is the DNA located in the mitochondrion, mitochondria organelles in a eukaryotic cell that converts chemical energy from food into adenosine triphosphate (ATP). Mitochondrial DNA is a small portion of the DNA contained in a eukaryotic cell; most of the DNA is in the cell nucleus, and, in plants and algae, the DNA also is found in plastids, such as chloroplasts. Mitochondrial DNA is responsible for coding of 13 essential subunits of the complex oxidative phosphorylation (OXPHOS) system which has a role in cellular energy conversion. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that human mtDNA has 16,569 base pairs and encodes 13 proteins. As in other vertebrates, the human mitochondrial genetic code differs slightly from nuclear DNA. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It als ...

Human Y-chromosome DNA Haplogroups
In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by specific mutations in the non- recombining portions of DNA on the male-specific Y chromosome (Y-DNA). Individuals within a haplogroup share similar numbers of short tandem repeats (STRs) and single-nucleotide polymorphisms (SNPs). The Y-chromosome accumulates approximately two mutations per generation, "one mutation in every 30 million base pairs" and Y-DNA haplogroups represent significant branches of the Y-chromosome phylogenetic tree, each characterized by hundreds or even thousands of unique mutations. The Y-chromosomal most recent common ancestor (Y-MRCA), often referred to as Y-chromosomal Adam, is the most recent common ancestor from whom all currently living humans are descended patrilineally. Y-chromosomal Adam is estimated to have lived around 236,000 years ago in Africa. By examining other population bottlenecks, most Eurasian men trace their descent from a man who lived in Afric ...

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] |
