Chromosome Complement: A Fertile Hybrid between Equus priewalskii and Equus caballus
Abstract
At the Zoological Garden of Antwerp it has been proved that when Equus prjewalskii is crossed with E. caballus the offspring is fertile. As expected, its diploid chromosome number is 65. The morphological differences between the parental and the offspring karyotypes are not great; therefore, meiosis in the hybrid was successfully achieved.
