In 405 samples taken in India in a 2005 study, 1.5% were G. [23] In a 2009 study covering mostly New Delhi and Andhra Pradesh 2% of 104 samples were G. [53] In another study in 2008 that concentrated on southern Indian locations, [54] less than 1% of 155 samples was G in Tamil Nadu, and the G percentage in Andhra Pradesh was 1% of 167 samples.
In August of 2015, a new chip was designed as a joint effort between Vilar, Genographic Lead Scientist, and Family Tree DNA. [7] In the spring of 2019, it was announced that the Geno project had ended, but results would remain available online until 2020. In July 2020 the site was retired.

The table below shows the human Y-chromosome DNA haplogroups, based on relevant studies, for various ethnic [dubious – discuss] and other notable groups from Europe.The samples are taken from individuals identified with the ethnic and linguistic designations shown in the first two columns; the third column gives the sample size studied; and the other columns give the percentage for each ...
A Y-DNA test analyzes similarities in Y-chromosome DNA markers, corresponding to specific locations on the Y chromosome. Markers have a Short tandem repeat (STR) that involve repeats of 2–5 DNA base pairs. At Sorenson labs, the number of STRs in a 36-marker haplotype was compared between the sample given and the database to determine relatedness.
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.
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 ...
