I recently found out that my mother had a relationship with someone and me and this person have far more in common both in personality and bodily characteristics than me and my father. I want to do a DNA test to make sure before I confront her about it, however I do not want to hurt my father in any way by doing so, is there any way I can do this to know for sure?

My boyfriend has a 3 yr old son from a previous relationship but he isn't sure if the boy is really his. The mother doesn't let my bf talk to the boy and surprisingly has NOT asked for any kind of child support. We WANT to take care of the little boy or see him regularly if it is my boyfriends. The boy is in another state. Where do we start with DNA tests and how much does it cost?

My daughter is almost 4 weeks old and she honestly looks nothing like me. All my close friends agree. I think she looks like one of my wife's co workers. They went on a business trip around the time my daughter was concieved. I do not want to acuse my wife and be wrong. I also do not want to ruin our relationship if Im wrong. Is there a way for me to get a dna test for me and my daughter without my wife's knowledge?
