:::Coyotes/wolf hybrids show a marked decrease in offspring viability after several generations, and jackal hybrids don't occur in the wild and also suffer reduced fertility and genetic abnormailties. Wolfdogs have no decrease in viability or fertility, and occur (relatively)commonly where feral dog and wolf populations overlap.
