There is always new DNA testing.
For genealogy purposes, this
technology basically began in 1996. You can now test your
father's history and
your mother's history through your own DNA!
Family Tree DNA has always been on top of the DNA testing
game. Currently, they are the only site that tests a
67 marker test for the Y
chromosome that is passed from father to son. They also have the
most
comprehensive Mitochondrial DNA test available
which analyzes the maternal
DNA.
Another thing that separates
Family Tree DNA from the other
testing sites is their largest DNA database which allows you to match with
others.
If you are looking for the newest of DNA testing capabilities
there is one good option.
