I don't see how this creates cycles, with a parentage graph. For cycles to exist, you would need to have time travel.

This seems to create a structure of the form. (If F is father and D is daughter, and I is the child they had).

    +---------------->I
    |                 ^
    |                 |
    F------>D----------

Which remains acyclic.

You are correct. Quoting the start of the highest ranking response, the person asking the question has "a fundamental misunderstanding of what a family tree is supposed to be."

Oops, I didn't mean to link to that downvoted answer...
