text: I had a biology teacher in high school say once that there was only one case of parthenogenesis (so-called vigin birth) in humans...Jesus Christ.  Parthenogenesis in vertebrates usually involves all-female species where the females lay diploid eggs that develop into diploid females.  Because human males have an X and a Y chromosomes and females two X's, the parthenogeneis explanation is impossible (unless Jesus was female).\n\nBut, in insects and some other animals, unfertilized (haploid) eggs develop into males - but this is impossible in humans.  So Jesus would have to have been diploid (that is if he existed) and we would have to assume that he got the Y chromosome from God (if he exists).
