Hi there!
So.. here's the thing abut DNA tests. They have a little disclaimer on them most of the time that says they are for entertainment purposes, and not to be taken for serious matters. Why? Because they are imperfect. Nine months ago, I ...
Did you just begin more modern tests as that drop occurred? I had a similar drop when I reached the high60s/70s series of test. It's not big deal and just required me to adjust to some of the newer tricks the test writers threw at me.
