As a male, I can only see the hg for my fathers paternal line and my mothers maternal line. This way I can only get two lines. If I would like to get four lines (for both of my parents) then I would need additional tests for my fathers maternal line and for my mothers paternal line (from a uncle). This will require one extra test set for sampling my father and one test for my uncle and it will cost much extra + customs if your international.

The most cost efficient way is therefore that your sample your father and one of your mothers brother for both the YDNA og mtDNA tests. This will be much more cost efficient, unless they pay for them self.
