Wouldnt surprised if it did come from her originally, she gets a ton of yotes.
I should pay her off to hold one if she ever finds another! hahaha

Coydog, probably. That's irish spotting. Just a genetic mutation that creates collie-like markings. The flecks on it's muzzle is ticking. Also happens with irish spotting.

Piebald actually isn't a form of luecism, in domestic dogs white-spotting is it's own separate gene and can range anywhere from Solid (dominant) to piebalds and extreme piebalds (recessive). You can think of it as solid colors being a capital S and piebalding/white markings being a lowercase s, if you've ever used Punnet squares. If this guy had parents who happened to carry piebalding (most likely from breeding with dogs somewhere in their ancestry) then there's a small chance one of their puppies would carry both piebald genes, letting this guy happen. It's quite rare in wild species, you're very lucky to be able to have a specimen like this! Though I agree, awful shame that they had to cut him up...

Not too much in coyotes... I do know that in wolves, the black-phase coloration they can sometimes have is actually a trait that originally was bred in from domestic dogs, and is a dominant trait. In dogs, one of their locus sets (pairs of alleles that determine color) is represented by the letter K. A capital K means black, so if a dog is KK, or Kk, the black will mask all other color - a black labrador, for instance, is a yellow lab with a K gene, so it appears black. If a dog has two lowercase, recessive Ks, kk, it will let patterns like agouti, sable, and etc show through. So the vast majority of wild wolves are kk, which is why they appear sable/agouti in coloration. But because somewhere in their lineage a dog passed on the K gene, and K is dominant, that's how you get these strains of black-colored wolves.
Now I don't know too much about coyote-specific genetics but I have to assume that it's the same story with them, as coyotes will interbreed with dogs (or, it's even possible that a coyote could have interbred with a black wolf and gotten that gene from there).

I don't think so considering white is like a "top layer" gene. White is OVER black in, for example, a border collie. It's not that black is "lost" in the areas where the dog appears white.
