If we would have been able to run a DNA test on the blood of Jesus what would we have found? Would it have proved that Mary was the mother of Jesus? Did the Holy Spirit deposit the fertilized egg in Mary’s womb or did he fertilize Mary’s egg?

I always assumed that the Holy Spirit fertilized one of Mary’s eggs. We have been given the genealogy of both Joseph’s heritage and Mary’s heritage, but is there any DNA of either of them in the blood of Jesus?
