Jesus' DNA

Here's another question from the skeptics. If God is the father of Jesus, what is Jesus' DNA like? Does God have sperm? If he doesn't, where did Mary get the DNA from that was needed to make Jesus? This would make Mary asexual and Jesus would then be a girl. No Y chromosome.   

 As a scientist, I have always said that I'd love to get a look at Jesus' DNA. We aren't given the biological details of Mary's pregnancy in the Bible  because (as the skeptics are so fond of saying) the Bible is not a science book. In other words, the details are not essential to the message of the Bible. All the Bible says is  "The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God." (Luke 1:35)

If God can create the universe, then he can certainly create a Y chromosome for Jesus' maleness inside Mary's egg along with the rest of the other half of Jesus DNA during this "overshadowing". (Don't you wish you could decide exactly what your son's DNA was like?)
