Sort of like how some coyote populations are around 4% of wolf ancestry. That doesn't mean that they are only 96% similar to “pure” coyotes - because coyotes and wolves are themselves over 90% similar in genetic DNA.
Wolves, coyotes and dogs are 100% of the same species in any case and can breed at will ~ provided everything is in place and they’ve checked it out with the pack and all that ~ and heat ~ must have heat!
