I know that per torah, if a (Jewish) man has relations with a woman who is niddah he is punished with kareit. I have been told that in this case the woman is also punished with kareit.
Is the woman's kareit dependent on the man's, or independent? If a Jewish woman (who is niddah) has relations with a non-Jewish man -- a man who is not subject to kareit because he's not Jewish -- then is she still punished with kareit?
