The analysis that has been conducted to provide your mother/fatherline results is completely different from the way that your family ancestry results have been analysed. Our mother/fatherline testing results in your maternal/paternal haplogroup assignment, which is your "branch" of the human family tree, from your mother's/father's side. You will share an ancient ancestor with everyone who shares your haplogroup.
Your mother/fatherline results are therefore interpreted in a different way. The percentages in your mother/fatherline results show you where in the world your haplogroup is most prevalent; it does not show how much your own DNA identifies with certain worldwide populations. So for example, if your mother/fatherline results say something like "England 10%", this means that 10% of the people that have been tested in England, happen to share the same haplogroup with you. Therefore, it is unlikely that your mother/fatherline percentages will add up to 100%.
