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. 
Comparison of divergent breeding management strategies in two species of semi-captive eland in Senegal
TLDR
The parameters of genetic polymorphism indicated much lower genetic diversity in Western Derby elands compared to Cape elands, and the coefficient of inbreeding was low in both species, and it is hypothesized that this could be a positive effect of strict population management of Western Derbyelands, which, despite the loss of genetic diversity, minimizes inbreeding.

An ancient hybridization event reconciles mito-nuclear discordance among spiral-horned antelopes
TLDR
A species tree reconstruction for the genus Tragelaphus is provided and it is shown that Scriptus and Sylvaticus are reciprocally monophyletic at nuclear DNA loci, comprising a single species across its African range. Expand

Unusually large sex chromosomes in the sitatunga (Tragelaphus spekei) and the blackbuck (Antilope cervicapra)
TLDR
Two members of theArtiodactyla, the African sitatunga and the Indian blackbuck, have now been found to have this peculiarity of extra large sex chromosomes, and theories concerning the formation of these outsized chromosomes are discussed. Expand
Chromosome studies in the superfamily Bovoidea
TLDR
The chromosome morphology of about 50 species of Bovoidea indicates an almost exclusive use of the Robertsonian fusion mechanism of karyotype evolution in this group of species which represent 30 different genera. Expand
Sex-chromosome translocations and karyotypes in bovid tribes.
Chromosomes of species from four bovid tribes are discussed in this paper. Two of the tribes are characterized by species with translocations or other unusual features involving the sex chromosomes. T
