Christmas DNA

Happy Christmas Everyone! Since it's Christmas and I've been reading a book on religious philosophy, here's a Christmas thought. We're told that Jesus was born to Mary even though she was a virgin. That is to say, she had never had sex, and so no sperm had ever entered her uteris to fertilise the egg.
