Genetics (deer or human) is far more complicated in reality than in Storm or FSW's arguments. Which in itself works in FSWs favor. Comparing this deer's DNA to a handful of deer from the area; or even to a database of deer from different regions, would still not prove wild vs. farmed. You could maybe say it is more closely related to deer from one area or another, but not if it was farmed. (This would be similar to human genealogy/ancestry test which suggest your ancestry based on a few markers in their database). The only genetic test that would prove this deer is farmed would require a database for all farmed deer, to which this individual deer could be matched. Ill assume if this exists FSW would've mentioned it by now.
