Forgive my difficulty I have expressing my thoughts, English is not my first language. Does anybody have any up-to-date info on the Alsace/Argentoratum region? I'm interested in this region because this is where Roman settlement is not known much in genetics due to the fact that they have the same R1b as Italy (u152).
I see that Alsace was a large Roman military settlement for 500 years as well as a major center of viticulture important to the Roman Empire.
Is the low level of J2 in Alsace because most of the merchants/soldiers in that time span probably came from northern/central Italy where R1b-u152 is highest already?
We look at Italy, and R1b-U152 is high in the north and central regions (of course it's high all over Italy). So if the majority haplogroup in Alsace (u152) is the same as the majority haplogroup in northern/central Italy (u152), don't you think Roman settlement left a bigger impact than a mere 5% J2 that is implied in Alsace? Do you get what I'm saying? Argentoratum was Gaulish, and Gaulish Italian as well as other Italian soldiers and merchants probably came and mixed since they were similar to the Gaulish people of Argentoratum.
If Romans brought and left the 5% J2 in Alsace, then they probably left a more significant amount of R1b-U152 there too because J2 is less frequent in north/central Italy than u152 already? But we can't tell that because Alsace was already mostly R1b-u152 already. So if we can't tell from DNA, can't we guess how much of an impact the Romans had in Alsace with ratios? For example, if northern Italy is 15% J2 and 60% R1b-U152... then that's a J2:R1b(u152) ratio of 1:4 in northern Italy. So if 5% of Alsace is J2, could 20% of the R1b-U152 in Alsace be from the 500 year-long Roman settlement? And if we assume maybe half of the soldiers in Alsace were not from the Italian peninsula, maybe 2.5% of the J2 was brought from the Italian peninsula and at a ratio of 1:4 then 10% of u152 in Alsace currently could be of Roman/Italian peninsula origin?
If you understand me great, if not let me know and I will try to be clearer.
