The quick answer is that they come from both.
Our genetic test does not trace back through your paternal and maternal ancestors for generations to tell you where your oldest relative comes from.
What we do is compare your DNA or genetic material information with the genetic information of numerous reference populations and ethnicities from multiple regions of the world. We analyze the genetic variants observed in the autosomal region of your DNA, commonly known as SNPs (single nucleotide polymorphisms). Each population has unique genetic variants, making this type of genetic marker very useful when determining your ancestry.
By comparing the SNPs in your DNA against those of the registered populations, knowing they have been inherited through generations of your family, we can calculate the origins of your ancestors. Since you have received the same amount of genetic material from both your father and your mother, the ancestry result we provide comes equally from both family branches.
The ancestry we provide is different from haplogroups and they should not be confused. The paternal and maternal haplogroups do indicate the specific line of origin of the father and the mother by taking fragments of the genome that can only be transmitted by that specific relative.
