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.
This page aims to assist Wikipedians working with biographical articles containing family trees. The most common way is to display a family tree on Wikipedia is as an ahnentafel by Template: Ahnentafel. However, there are other options. This page originated in examples taken from a discussion on the Village pump in March/April 2005 (see Talk ...
The family tree of Louis III, Duke of Württemberg (ruled 1568–1593) The family tree of "the Landas", a 17th-century family [1]. Genealogy (from Ancient Greek γενεαλογία (genealogía) 'the making of a pedigree') [2] is the study of families, family history, and the tracing of their lineages.
Comparison of DNA sequences allows organisms to be grouped by sequence similarity, and the resulting phylogenetic trees are typically congruent with traditional taxonomy, and are often used to strengthen or correct taxonomic classifications. Sequence comparison is considered a measure robust enough to correct erroneous assumptions in the ...
A genealogical DNA test is performed on a DNA sample obtained by cheek-scraping (also known as a buccal swab), spit-cups, mouthwash, or chewing gum. Typically, the sample collection uses a home test kit supplied by a service provider such as 23andMe, AncestryDNA, Family Tree DNA, or MyHeritage. After following the kit instructions on how to ...
Molecular phylogenetics (/ m ə ˈ l ɛ k j ʊ l ər ˌ f aɪ l oʊ dʒ ə ˈ n ɛ t ɪ k s, m ɒ-, m oʊ-/ [1] [2]) is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships.
Genetic testing, also known as DNA testing, is used to identify changes in DNA sequence or chromosome structure. Genetic testing can also include measuring the results of genetic changes, such as RNA analysis as an output of gene expression , or through biochemical analysis to measure specific protein output.

In 2006, FamilyTreeDNA bought out the assets of DNA-Fingerprint, which was a German paternity testing company that offered à la carte testing to the genetic genealogy testing community. With this buyout, Thomas and Astrid Krahn, who had owned DNA-Fingerprint, moved to Houston, Texas, and helped open the Genomics Research Center.
