Abstract
The offspring of the cross bongo (Boocercus euryceros), 2n = 33 x sitatunga (Tragelaphus spekei), 2n = 30, has proved to be fertile. This fertility shows that the relationship between the karyotypes of the parental species is a simple one, despite the different diploid numbers and a different sex chromosome determinism, XX/XY in the sitatunga, XX/Y-to-autosome translocation in the bongo:meiotic processes and gametogenesis are not impaired in the hybrid.
