Men have one X chromosome and one Y chromosome (the Y making them male). While women have two X chromosomes and no Y. It is the Y that is passed from father to son, to son, to son, etc.
So, by looking at your Y chromosome type and comparing it to Y chromosomes types found all over the world and in all the different races, we can evaluate where your great paternal ancestors originated from and where they are distributed in the world today.
Because this test uses the Y chromosome, only men can have this test. A woman wanting to trace her fathers genetic ancestry could gain this information by using a sample from her fathers close relative ie brother, son etc.

Ancestry by DNA
This test gives you a general insight into your ancestral makeup from four major racial-geographical groups based on your ancestors up to 5 generations back. This is different to the Y and Mito lines, which give you a precise pinpoint of your ancestors to a much greater depth and age.
