In spite of the strong possibility that we are being trolled, I will offer a serious reply.
My first encounter with inter-racial (a term that I despise) marriages was while I was serving in the Air Force, and what I noticed was that the children of those marriages were usually better looking and, dare I say it, smarter than either of the parents. A few years later, while still overseas, I was taking an upper-level sociology course, and I asked the professor about that. He promptly answered that the reason for that was “hybrid vigor,” now called “heterosis.”
Those who want the mind-numbing full explanation can visit the Wiki article here:
en.wikipedia.org/wiki/Hybrid_vigor . The short explanation is that when the parents are from the same or closely related gene pools, there is a higher chance of matching lethal or harmful recessive genes, which means higher chances of negative traits in the offspring (thus the prohibition against incest). However, when the parents are from different gene pools, the harmful recessives are different, and there is less chance of reinforcement. Thence – prettier, smarter, healthier kids.
Sometimes it seems from the Old Testament that God wanted the Israelites to have it in for other races – “Kill all the Canaanites, no descendant of a Moabite can enter the congregation to the 10th generation,” etc. However, the discrimination was not race-based, but faith-based. Thus Rahab, a Canaanite, was not only allowed to survive; she married a leader of the tribe of Judah and became an ancestress of both the Davidic royal line and the Messiah. Likewise, David, only three generations removed from his Moabite ancestress, was not only allowed into the congregation; he became king.
Frequently we can determine the will of God by what happens in nature. For example, it is not God’s plan that there be a cross between daffodils and oak trees, and any attempt to make such a hybrid would fail. Dogs cannot cross-breed with cats. Within humanity, God’s will, expressed in both testaments, is that believers marry within the faith, and we see that mixed-faith marriages, or marriages between believers and complete non-believers, have problems. However, marriages between humans from different gene pools produce superior children (I’m beginning to sound like a eugenist :bigyikes

. That, to me, speaks volumes.
OP, if yours was a serious request, I would advise that you stay out of your children’s private choices.
