I'm sure someone on here with much more knowledge on DNA can help me with my question. My bio sister and I did DNA test a while ago and we are half sisters. We have the same mother. Rumor has it that one of my mom's brother-in -law was my father. If we did DNA on here would it show us as cousins if that was a true fact? I was adopted but my tree shows our mom and her husband and most of his family.
Thanks for anyone answering my question!!!
