I’ve had full spectrum, yDNA and mtDNA tests done. Surprising results. As well as determining the origin of your haplogroup, the tests also provide matches to other people and their ethnicity. When replicated DNA creates mistakes in the code - basically like typos. When compared with other people, if they have the same typos it shows you are related to them.[/quote]
If you don’t mind me asking what were your results? Did they match your expectations or was it a complete surprise? [/quote]
The yDNA(paternal line) and full spectrum results were as expected. However the mtDNA(maternal line) and a lot of the ancestral origins matches were a complete surprise. It’s important to note that mtDNA and yDNA are only a small part of your DNA though.
I’m confused by this statement. How does mtDNA+yDNA/=100% of your DNA?[/quote]
mtDNA is only the DNA from your direct maternal line. It comes from your mother, your mother’s mother, your mother’s mother’s mother etc. As you have have two parents, four grandparents, eight great grandparents etc. it is only a small part of your DNA. Additionally it is passed on virtually unchanged from one generation to the next. It’s the same with yDNA but on the paternal line. And yDNA is only passed on to males.
Autosomal DNA by contrast includes both parents, all four grandparents, all eight great grandparents etc.
See attached picture of maternal line for why it is only a small part of your DNA.
I haven’t studied or really read much about this topic.
So, Autosomal DNA contains DNA from your mothers side that is not contained in the mtDNA i.e. fathers DNA on the maternal side? And vice versa on the fathers side?
So when the last male of a name does not have a son, but has daughters, the yDNA of that man ends?
