FTDNA is the only good option for Y-DNA testing (I recommend testing at least 37 markers) and mtDNA (full sequence is best if you can afford it). FTDNA also guarantees storage of the unused DNA, making it an excellent choice for elderly relatives whose DNA you may want to test further down the road.
Highly accurate DNA parental testing became available in the 1980s with the development of RFLP. In the 1990s, PCR, developed in 1983, became the standard method for DNA parental testing. A simpler, faster, and more accurate method of testing than RFLP, it has an exclusion rate of 99.99% or higher.
