I want to find out my EXACT ancestry heritage...what is the best and cheapest way to do it? I know I am korean, with some japanese from when they invaded korea, and some Caucasian when my grandparents came to america...but I would like to know what percent of exactly what...thanks!

I was contemplating taking the african american ancestry dna test and I was wondering if it was a valid way to trace your heritage. People are so crooked now a days and well....I just don't want to end up wasting 0 on bogus results. I really feel the need to know more about my ancestors and exactly where they originated. Please help, if you can. Thanks.

I have yet to get a clear answer on what defines a jew....especially when in concerns immigration to Israel.
If a DNA test shows someone to be of (Ashkenazi Jew) a certain haplotype, does this "hold any water" when documenting your heritage in immigration?
