Thread: DNA testing for relationship

Hi all,

Just was curious. I'm just wondering how detailed we can go in materinty/paternity testing.

For example, can we test the mitochondrial DNA of our cousin (obvisouly on the femail side) and tell they are our cousin's? Can we distinguish first cousin's from second/third cousin's/fourth? etc.

Could we distinguish our great great great grandmother form our great great grandmother? How many generations can we test?

Thanks,
Tom
