Relative Genetics Launches New Free Online Y-Chromosome Haplogroup Predictor Service; Service Will Enable Users to Identify and Understand their Particular Genetic ''Branch'' of the Human Genealogical ''Tree''.SALT LAKE CITY -- Relative Genetics, a leading global provider of genetic testing Genetic Testing Definition A genetic test examines the genetic information contained inside a person's cells, called DNA, to determine if that person has or will develop a certain disease or could pass a disease to his or her offspring. solutions for private companies, individuals, family organizations and genealogists, today announced that it has launched a Y-chromosome haplogroup predictor service on the company's Web site, www.relativegenetics.com. The new free service will allow users to learn from which deep genetic ancestral group (haplogroup) they may have originated. Y-chromosome haplogroup, sometimes called "macrolineage," can be defined as a group of related Y-chromosome haplotypes that share a common deep genetic ancestral origin. Haplogroups can be understood as large branches on the human Y-chromosome phylogenetic tree phylogenetic tree Diagram showing the evolutionary interrelations of a group of organisms that usually originated from a shared ancestral form. The ancestor is in the tree trunk; organisms that have arisen from it are placed at the ends of tree branches. . A Y-chromosome haplotype haplotype /hap·lo·type/ (-tip) the group of alleles of linked genes, e.g., the HLA complex, contributed by either parent; the haploid genetic constitution contributed by either parent. hap·lo·type n. (i.e. haploid haploid /hap·loid/ (hap´loid) 1. having half the number of chromosomes characteristically found in the somatic (diploid) cells of an organism; typical of the gametes of a species whose union restores the diploid number. genotype) is a set of genetic markers (i.e. mutations) inherited through the paternal line, which provide a distinct genetic pattern for that paternal line. Relative Genetics also provides testing services for individuals who would like to know their exact Y-chromosome haplotype. Haplogroups have been shown to correspond to early human migrations and can be associated with various worldwide geographic locations. Haplogroups, defined by markers found in male (Y chromosome Y chromosome, n a sex chromosome that in humans and many other species is present only in the male, appearing singly in the normal male. It is carried as a sex determinant by one half of the male gametes. None of the female gametes contain a Y chromosome. ) and female (mitochondrial DNA Mitochondrial DNA (mtDNA) is the DNA located in organelles called mitochondria. Most other DNA present in eukaryotic organisms is found in the cell nucleus. Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived from the ), link the group together through the markers that first appeared in the group's most recent common ancestor The most recent common ancestor (MRCA) of any set of organisms is the most recent individual from which all organisms in the group are directly descended. The term is most frequently used of humans. . "Using Relative Genetics' Y-Chromosome Haplogroup Predictor, when a user enters his Y-chromosome haplotype information, Relative Genetics can predict from which deep genetic ancestral group the user may have originated," said Darlene Odenwalder, a genetic genealogist at Relative Genetics. Relative Genetics is a leading provider of genetic genealogical testing services such as Y-chromosome haplotyping, which includes a laboratory report, an explanation of the results, a Y-chromosome haplogroup prediction, an explanation of haplogroups and a distribution map of the haplogroup.
