Divine DNA

Today D. and I were discussing Jesus' genes. If Jesus was truly God's son, were his genes then 50% from God and 50% from Maria, or 100% God? The first scenario would mean that God and Maria were of the same species, i.e. both human, which would be unexpected. The second scenario implies that even the egg came from God, which would mean that God is a woman! The second option seems more likely, and none of both would please the Christian clergymen.
