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 (October 31, 2005) - Relative Genetics, a leading global provider of genetic testing 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. A Y-chromosome haplotype (i.e. haploid 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) and female (mitochondrial DNA), link the group together through the markers that first appeared in the group's most recent common ancestor.

"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.
