Hi list, I have a question about DNA research for women. I have an adopted aunt, who as the story goes, is actually my sister. Would DNA testing prove whether or not we share the same father? And would it show if her father is actually my grandfather(another version of the story)? We know that she is the daughter of one of these two men (my father or grandfather), but don't know which. Would DNA testing of myself and my aunt answer these questions? Carrie in Colorado Carrie Marsh <carrie1@attglobal.net>
