FamilyTreeDNA is a division of Gene by Gene, a commercial genetic testing company based in Houston, Texas. FamilyTreeDNA offers analysis of autosomal DNA, Y-DNA, and mitochondrial DNA to individuals for genealogical purpose. With a database of more than two million records, it is the most popular company worldwide for Y-DNA and mitochondrial ...
Generally, testing only the HVRs has limited genealogical use so it is increasingly popular and accessible to have a full sequence. The full mtDNA sequence is only offered by Family Tree DNA among the major testing companies [26] and is somewhat controversial because the coding region DNA may reveal medical information about the test-taker [27]
Data on the racial distribution of profiles suggests that 8.6% of the entire African American population is present in the database compared to only 2% of the white population. [ 19 ] On the other hand, genetic profiles from direct-to-consumer databases and GEDMatch consist of 75% white individuals from Northern European descent. [ 5 ]
Millions of people use genetic testing companies like 23andMe to learn more about their ancestry and health. But a new data breach is highlighting the risks of having your ancestry information ...
Thousands of Family Tree DNA customers have submitted their mtDNA sequences for use in scientific studies, [4] including those led by Behar and Brook. Additional samples were provided by the National Laboratory for the Genetics of Israeli Populations.
In the 2014 study, of the three successfully generated SNP profiles of Neolithic Starčevo culture samples from Vinkovci, two belonged to Y-DNA haplogroup G2a-P15 and one to I2a1-P37.2, which could indicate G2a as potential representatives of the spread of farming from the Near East to Europe, while I2a as Mesolithic substratum in Europe.

An open reading frame (ORF) is a reading frame that has the potential to be transcribed into RNA and translated into protein. It requires a continuous sequence of DNA which may include a start codon, through a subsequent region which has a length that is a multiple of 3 nucleotides, to a stop codon in the same reading frame.
