Sure he can, and I'm looking at it, though at first glance it appears to just be DNA Haplogroups, which do a poor job of giving a coherent definition of "caucasian" and a worse job of qualifying as a subspecies.

Any definition of a "subspecies" beyond "the level of taxonomic order beneath a species" is sheer scholasticism. ...

... Real taxonomic order is inherently messy, because evolutionary biology is. Concepts are scientific only if they follow the phenomenon.

... If there's a coherent pattern of genetic distance, it merits a word -- unless people are deliberately trying to obfuscate (which is not untypical).

I mean, Elizabeth used such a word - "haplogroup". The attempt to revitalize the related but outdated word "race" instead seems to do little work besides let older, some not-even-claiming-to-be-scientific concepts of race free-ride on only formally similar premises

"Race" hasn't been mentioned in this conversation, although there is no good reason why it shouldn't have been. ...

That's an endearingly paranoid way of trying to ignore the fact that "subspecies" implies a bar that is in no way met by y-chromosome haplogroups.

It doesn't imply any kind of "bar". It's a flexible taxonomic heuristic.

Unless you're both arguing that all taxonomic order breaks off completely at the level of the species, this is nonsense.
