April 3, 2013: Hello, I did an African mtDNA ancestry test in hopes of pinpointing a tribe of my African lineage (that's what the company claimed they do). I'm an African-American woman. I received my results and it said that my lineage was of European descent, non-African. What does this mean? I was very confused because I'm clearly black as are my parents and grandparents before them.  Does that mean there is no African in me at all or that they just didn't find it?

January 25, 2012: My extended family just had 23andMe testing and a younger brother and older sister found out they probably aren't brother and sister. They are OK with this but we are trying to figure out how they are related. The results show they are 25% related except on the X chromosome where they share no DNA. Most likely given what we know about our family's history they are half brother and sister. Can you tell from this information if they share a mom or dad?
