Genetic DNA Markers
There are 3 types of inheritance pattern categories that these markers follow; the Autosomal DNA line, the paternal DNA line or the maternal DNA line.
The Autosomal DNA line makes up the majority of who we are. It is composed of all the DNA in the cell except the X-chromosome, the Y-chromosome and the mtDNA.
You inherit 50% of your autosomal DNA from your mother and 50% from your father.
The Y-chromosome markers are paternally linked. They are passed from father to son.
The mtDNA markers are maternally linked. They are passed from the mother to all of her children. Then, only the female children pass it on to all their children, and etc.
It is less expensive to test just the Y- or the mtDNA, but then you will only be able to establish and show future generations either the maternal line or paternal line of ancestry.
