Caliber:
Okay, but not sure if you are making a point, or just passing on information. This was a test for blood type---not a check for geneology through DNA. If the blood type is AB, then one allele was inherited from father and one from mother. We are talking blood type here, not heritage.
But yes, if he inherited all of his alleles from Mary, and he was type AB, then she would have also had to have been type AB. And as the article pointed out, so would 18% of present day population of Northern Palestine. Not rare in that area (I didn't check the facts with any other source, just going off your article)
Yet, if he inherited all of his alleles from Mary--??--would that not require that he too be female? She would not have a y chromosome to pass on to him. Seems much more logical that a father passed on half the genes----unless a Y chromosome was somehow miraculously inserted? Or perhaps he wasn't exactly human----in the same way we are human? but then, would that not negate just about everything in the gospels? Really, our genetic make-up is what makes us human. If some new form comes along with a completely unique make-up, would that be H. sapien? Of course there are still humans that are born with the wrong number of chromosomes, and they are human, but that is just one variation.
