O Great Barbarian, if I may bring this conversation back to biology for a moment, I’d like to ask you a question about the Incarnation. I realize you many not be a geneticist,
Biologist. Bacteriologist. And um, well, operations research.
but you may be able to direct me to one who could answer some of these questions. What is your take on the genetics of Mary’s virginal conception of Jesus?
Miraculous. I have no idea where the Y chromosome came from, if that’s what you’re getting to.
(1) Was Jesus haploid or diploid? Could he haver been parthenogenetically haploid?
Nope. Wouldn’t be a “he” if he was. The X chromosome is absolutely essential for human life, but the Y is required to make a male. And I don’t think a haploid human could survive at all. Probably wouldn’t even form an embryo.
(2) If diploid, was the “divine” half of his chromosomal load genetically related to his human semitic ancestry, or not?
We can only speculate, but given that the angels who appeared to humans from time to time weren’t considered unusual in appearance, I suspect that the genetic characteristics were pretty much standard for the area at the time.
(3) If God miraculously constructed a haploid genome that was then syngametically conjoined with Mary’s, was this genome merely a simulacrum of a semiitic haploid genome, or was it real?
Hmmmm… if God miraculously created a human from scratch, would it be merely a simulacrum of a human or would it be real? Don’t really know how to answer questions like that. I guess, if God wanted to make it real, He could.
(4) If it was a real half-genome, from what gene pool might the Holy Spirit have drawn the chromosomes, including Jesus Y chromosome?
If he had a sense of humor, I suppose Joseph would have been as good a source as any (Barbarian nervously anticipates a good smiting)
(5) How would the mechanics of syngamy work?
Not at all, as far as I know. Apparently, there are some tumors that are haploid, or nearly so. But I never heard of a haploid human. Probably not possible.
Of course, if we simply opt for Mary’s miraculous conception of Jesus in terms of “overshadowing by the Holy Spirit,” we could sidestep these genetic issues entirely. However, it seems crucial to safeguard the full humanity of Jesus, in which case these biological questions are necessary, and fascinating.
Yep. I’ve wondered about that, myself. Just can’t say. I have to say, it would be interesting to have a little DNA from Jesus, wouldn’t it?
I don’t know of a theologian who has tacked this issue, and I’d be interested in references if you know of such.
I’ve heard a lot of low-level speculation from people who really didn’t have the theological or scientific stuff to contribute much. I just don’t know.
