How does DNA testing help genealogical research?
A.) The YDNA testing (which is primarily what our project uses) pulls a series of markers from the DNA pattern in the y-chromosome. The y-chromosome is passed from father to son only and remains nearly unchanged over the course of hundreds of years. This means that the Y-chromosome a man carries matches almost exactly, for example, with that of his 9th-great-grandfather. This helps identify (or connect) various “possible” cousins together, by indicating a common ancestry.
