I don't know about the Coyote, Coywolf genetics, but I do know in the recent years I have seen "Coyotes" as I have called them, become incredibly bold.
I'm in Southwestern Ontario, last fall for example while deer hunting I had a coyote walk into a field I was watching right before dark. I shot at it, a fair ways out, and presumably missed it, is I seen a coyote on the dead run heading out of the field after the shot. I gathered things up, cased my rifle, as required here in Ontario, and headed to the area where the coyote was. Another stepped into the field, I still had a minute or two of legal light left, so I uncased my rifle, and quickly shot at it, same thing, it tore off. (This story does nothing to tell of my shooting skills, LOL) while watching this coyote run off, another ran past me from behind, less than 20 yards away. I cased up my rifle again, as legal light was ending. I walked down where the first coyote was, and looked briefly for any sign of a hit, by this time I had to turn on a flashlight. I looked for a minute or 2 and then noticed something moving about 30 yards away. I pointed the flashlight in to watch another coyote circle completely around me, staying about 30 yards away the whole time.
Never have I seen coyotes this bold. A year early a couple of friends of mine in this same area had coyotes circle them while dragging a deer out, the coyote even came close enough to bite the hind legs of the deer as it was dragged. They actually uncased one of their rifles and fired at it to scare it off.
This is odd behavior for coyotes, at least in my experiences with them.
