Negative ghostrider - they are all Canis lupus. Genetically all the various breeds represents reductions in the genetic code variations available, but the genomes map the same.
They are all the same species. Wolves, coyotes and Paris Hilton’s purse dog. One could argue domestic dogs are a subspecies, but that is just for the convenience of taxonomy, not genetics or biology.
p.s. I am a recovering physiologist by education.
Negative. Coyotes are not wolves. There are genetic differences, obvious morphology differences, and behavioral differences. And they rarely interbreed, but they are capable of doing so.
Aren’t coyotes Canis latrans, a different species than wolves/dogs, Canis lupus?
Mules have fertility problems but offspring are not unknown. Are donkeys and horses the same species? Zedonks also can sometimes produce offspring. Are zebras and donkeys the same species?
One could also argue that Paris Hilton’s purse dog and a Great Dane are different species. Tab A will not fit into Slut B!
