Incest has been proven as dangerous for the children who might be born out of that relationship because they might have inherited diseases like those who can't stop bleeding. The Royal families already proofed it. Even 1st cousin's is nowadays incestrial (but not according to the Bible).
The problem with the prohibition of Jewish intermarriage is often that reason that the Rabbi's are concerned that the person who intermarries looses his/her identity. If the mother is not Jewish or does not convert her children won't be Jewish. The mother is more important as you can be sure who gave birth to the child but not who gave the sperm.
