Me, my sister, mum and dad have all done DNA tests.
The confusing thing is, my sister and I have nearly 50% shared DNA with each parent, about 45% with each other, but we both have ethnicity estimates our parents don't?
My sister has over 45% "English" DNA, neither me nor either of my parents has any, my dad and both have 75+% Irish, Scottish and Welsh, and my mum around 60%.
I have a small % of "Mesoamerican" DNA which neither of my parents or sister share?
Any ideas how that works, or where I could find that info?
Also, I saw above that 18% ethnicity indicates a grandparent with that ethnicity, my mum has around 20% Scandinavian DNA, and nearly 20% Eastern European, does that mean that DNA comes from more recent ancestors than I'd assumed? I'd put the Scandinavian in particular down to ancestors with large amounts of viking DNA, breeding other ancestors with large amounts of similar DNA, passing it on, and on?
