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.
GenoChip is specifically designed for anthropological testing and includes SNPs from autosomal DNA, X-chromosome DNA, Y-chromosome DNA and mitochondrial DNA (mtDNA). The design of the new chip was a collaborative effort between Wells of National Geographic, Eran Elhaik of Johns Hopkins , Family Tree DNA , and Illumina .
The study of the genetics and archaeogenetics of the Gujarati people of India aims at uncovering these people's genetic history.According to the 1000 Genomes Project, "Gujarati" is a general term used to describe people who trace their ancestry to the region of Gujarat, located in the northwestern part of the Indian subcontinent, and who speak the Gujarati language, an Indo-European language.

The field of genetic genealogy and DNA sequencing has permitted ordinary people to make use of DNA testing to establish some evidence for their ancestral origins. Thousands of Family Tree DNA customers have submitted their mtDNA sequences for use in scientific studies, [4] including those led by Behar and Brook.
Siberian origins are still visible in the Sámi, Finns and other populations of the Finno-Ugric language family. [2] An abundance of genes has journeyed all the way from Siberia to Finland. [3] As late as the Iron Age, people with a genome similar to that of the Sámi people lived much further south in Finland compared to today.
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.
