Reproductive isolation from a cross between a horse and a donkey or between a mare and a donkey, respectively. These animals are nearly always sterile due to the difference in the number of chromosomes between the two parent species. Both horses and donkeys belong to the genus "Equus", but "Equus caballus" has 64 chromosomes, while "Equus asinus" only has 62. A cross will produce offspring (mule or hinny) with 63 chromosomes, that will not form pairs, which means that they do not divide in a balanced manner during meiosis. In the wild, the horses and donkeys ignore each other and do not
Equus (comics) system is filled with synthetic steroids, adrenaline, and endorphins. The artificial portions of his anatomy include three grades of soft plastic that Superman had never seen before prior to his first encounter with Equus. Equus' mechanical components are powered by a system of oligotronic solar powered fuel cells controlling seven different senses, and his nervous system is powered by enough electricity to power a city block. He is capable of extending five razor-sharp claws from the knuckles of both of his hands, in a manner similar to the character of Wolverine. The claws corresponding to his fingers are approximately a
