Mixing the chromosomes of horses and mules causes each mules and hinnies to be sterile, besides on a couple of recorded events. And since “species” is technically outlined as “a gaggle of dwelling organisms consisting of comparable people able to exchanging genes or interbreeding,” mules and hinnies will not be thought of species.
