Probably not all that different from the swine that infest much of Texas.

Yes, very similar. Particularly in that they are crosses and when bred back you may get any combination of the traits of the grandparents. We see feral hogs that are jet black, spotted, and snow white (although the white ones tend not to last long due to their visibility). More often than not the piglets are striped and look for all the world like wild boar, but may take on varied color as they grow.

two generations ago, it was a barnyard critter

There are still some "red" meat hogs grown around. One that comes to mind is the red wattle. Seems like a lot of trouble just to get the same!

Red Wattle crossbreeds taste delicious and can get big at a young age. Too bad the teeth are not as impressive as the body size.
