December 16, 2014: My mother who recently passed away was adopted at birth and I have been searching for her biological family.  I recently received my results from Ancestry DNA and was matched with a gentleman it says is likely my first cousin.  He is 83 however and I'm 30 so it seems like the age might be a little off for that to be the relationship.  I'm just curious if it's possible for them to mistake him for a first cousin when there is a different relationship?  Is it possible for him to instead be my mother’s sibling, my uncle?  What other possible relationships could it be if any?

September 3, 2014: I am interested in finding out what genetic testing could possibly tell me about my father. I have a brother (shared maternal, different paternal) who will be tested as well. In reading through other responses I understand statistically we should be 25% related. Would the differences in our testing isolate the DNA I inherited from my father vs the differences we get from our shared maternal line mixing?

February 12, 2014: I am a dog breeder and the question of line/inbreeding comes up often with fellow breeders. Here is my question—"Is there more chance of genetic flaws, undesirable diseases, etc. in mating a Mother to Son versus Father to Daughter?"
