My sister and I have the same mother, but my sister's biological father is our mother's brother, so is my sister just a half-sister, or something like 2/3 or 3/4 or some other fraction of a sister?

genetically speaking, your sister is your mother.

Wait, is your sister fruit of incest? Dude, that's disgusting and how is the dynamic of your family? I'm genuinely curious, what did your father do to discover and what did your grandparents did?
