I found this really interesting idea in which your sent a kit to retrieve a blood sample, and in turn you get a picture of your DNA. Honestly I think this is really a neat idea. Is it cheap, that would be a negative!
If I could I would get my daughter and myself done. It would be neat to compare our DNA.. since she is a part of me...
