Had a family member do one of those ancestry dna tests for him and his wife. Wife's came back with "trace" amounts that showed African and Jewish descent. No one saw that one coming as they're Caucasian with a "C". I said great now you can celebrate Hanukkah and Kwanzaa along with Christmas. Everyone got a laugh.

I am afraid that if I took one of those tests that it might show some chromosomal damage because my mother was a Democrat.
Getting the results of those tests can be rough sometimes.
