You ask, "What Genes denotes a particular religion?"
This isn't about a religion. It is claimed that this piece of material was the very shroud that wrapped Our Lord.
If this is true, Our Lord was Jewish. There are DNA markers for those descendants of the tribes. Further, Our Lord was specifically a descendant of a specific tribe of Israel - Judah.
I simply asked of the purported blood on the Shroud has been tested to see if it is genetically Jewish blood. If it is tested and doesn't have the Jewish markers, it is not the shroud of the Savior.
Ping: Godzilla, been a while and hope you are very well. I have some vague memory that at one time in the past you posted material about Jewish DNA markers. If that was you, do you have anything to contribute to this discussion?

And my point is that there are no distinctive markers that say this blood is "Jewish" from any other semitic blood in the middle east. There are no specific DNA markers that will state categorically that this person is Jewish. We can state that the blood genotype is AB negative which is a good indicator as it is much more likely to be found in that region and among those people of Middle Easter descent than anywhere else in the world. But the DNA is now too degraded to do much more after 2000 years or so.
Somewhere on the Shroud there may be some that is not, but we do not have full access to the Shroud to find it.
there are dna haplotypes that identify regions of the world that have been used to map human migrations. there has also been a lot of dna studies of groups claiming Jewish ancestory (Lembas, Ashkenzi, etc), so identifying specific jewish related markers is possible. The key is whether or not enough dna survived to enable the identification of the haplotype (effects from exposure to fires, air, etc).
