Under the sub laws of Noach
8 "Against [a man] lying carnally with his father." Negative Mitzvah 351 Leviticus 18:7 "Do not act immodestly with your father"
Although I'm not sure if this also means it's prohibited for a daughter to do the same, and in the other relations mentioned there I didn't see a mention of a original for father to daughter, only from son to mother
So is it prohibited to bnei Noach, or not? I wasn't able to find an explicit source
