A genealogical DNA test is a DNA-based 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 ethnic mixture of an individual. Since different testing companies use different ethnic reference groups ...

Currently the YHRD database recognizes four separate "metapopulation" structures: national, continental, linguistic/ethnic and phylogenetic affiliation with several categories within. In population genetics the term metapopulation describes discrete spatially distributed population groups which are interconnected by geneflow and migration. [8]
Based on data from "A unified genealogy of modern and ancient genomes". [62] Several methods to examine and quantify genetic subgroups exist, including cluster and principal components analysis. Genetic markers from individuals are examined to find a population's genetic structure.
GEDmatch was founded in 2010 by Curtis Rogers, a retired businessman, and John Olson, a transportation engineer, [4] in Lake Worth, Florida, [5] with its main purpose being to help "amateur and professional researchers and genealogists", including adoptees searching for birth parents.
Cowboy Names Go Next-Level. Call it the Yellowstone effect. "One of the biggest trends we’ll see for baby boy names in 2025 are 'Country Rebrand' names," says Sophie Kihm, editor-in-chief of ...
For example in human genetics, genome-wide association studies collect genotypes in thousands of individuals at between 200,000-5,000,000 SNPs using microarrays. Haplotype estimation methods are used in the analysis of these datasets and allow genotype imputation [ 1 ] [ 2 ] of alleles from reference databases such as the HapMap Project and the ...
