Dunno the rest of the genetics, but I see lots of feral hogs, fairly tame ones inside the city limits, a couple of sounders rest up in the brush within 50 yards of a busy bike path in the Missions park, you can walk right up on 'em. Sometimes they come up our back alley at night.
The most common colors here are black, and a sort of piebald tan and black. Might be sex-linked, I don't recall seeing a tan and black adult boar.
The REALLY huge boars have long straight backs, about like domestic pigs. Only a very few of them.
Their tracks are just regular pig tracks.
