G- and C-banded karyotypes of the genus Oryx were compared using the standard karyotype of Bos taurus. Chromosomal complements were 2n = 56 in O. gazella gazella, 2n = 58 in O. g. beisa and O. g. callotis, 2n = 56–58 in O. dammah, and 2n = 57–58 in O. leucoryx. The number of autosomal arms in all karyotypes was 58. Nearly all variation in diploid number was the result of three independent centric fusions, but one 2n = 57 specimen of O. g. gazella deviated from the normal complement of 2n = 56… 
Chromosomes of the antelope genus Kobus (Artiodactyla, Bovidae): karyotypic divergence by centric fusion rearrangements
TLDR
Several centric fusions were related by monobrachial chain-IV complexes; however, records of hybridization indicate that reproductive isolation between at least certain species of Kobus is incomplete, which supports the validity of these taxa, as well as the need to manage them as separate populations.
Centric fusion polymorphism in captive animals of family Bovidae
TLDR
The study showed that 13% of investigated individuals were polymorphic for the centric fusion and demonstrated the important role of cytogenetic screening in captive animals at zoological gardens.
Karyotype, centric fusion polymorphism and chromosomal aberrations in captive-born mountain reedbuck (Redunca fulvorufula)
TLDR
The study demonstrates the relevance of cytogenetic screening in captive animals from zoological gardens, and finds variation in the diploid number was found to be due to polymorphism for the centric fusion 6;10.
Molecular phylogeny and chromosomal evolution of Alcelaphini (Antilopinae).
TLDR
Patterns of chromosome evolution, reconstructed using a probabilistic approach, suggest that chromosome changes leading to speciation in Alcelaphini do not exclusively involve consecutive reduction of diploid number through centric fusion but also the losses and reversions of Rb translocations in Beatragus and Damaliscus lineages.
Comparative Analysis (Hippotragini versus Caprini, Bovidae) of X-Chromosome's Constitutive Heterochromatin by in situ Restriction Endonuclease Digestion: X-Chromosome Constitutive Heterochromatin Evolution
TLDR
In order to characterize the X-chromosome CH in non-Bovinae species – Hippotragini and Caprini tribes – using restriction endonuclease digestion on fixed chromosomes and sequential C-banding, the technology showed to be more evolutionary informative than the classical approaches.
Homologous fission event(s) implicated for chromosomal polymorphisms among five species in the genus Equus
TLDR
Evidence is reported that the polymorphism involves the same homologous chromosome segments in each species, and that these chromosome segments have homology to human chromosome 4 (HSA4) and that this polymorphism is either ancient and conserved within the genus or has occurred recently and independently within each species.
Oryx callotis (Artiodactyla: Bovidae)
Abstract: Oryx callotis O. Thomas, 1982 (fringe-eared oryx) is a relatively large, long-bodied bovid, with an appropriate common name because of its distinguishing tufts of hair extending from the
Three genetically divergent lineages of the Oryx in eastern Africa: Evidence for an ancient introgressive hybridization
TLDR
Findings from partial mitochondrial DNA control region and cytochrome b sequences of Oryx beisa analyzed are interpreted in terms of an ancient hybridization and introgression between two formerly isolated taxa of O. beisa.
Effect of species-specific differences in chromosome morphology on chromatin compaction and the frequency and distribution of RAD51 and MLH1 foci in two bovid species: cattle (Bos taurus) and the common eland (Taurotragus oryx)
TLDR
The formation of centric fusions during karyotype evolution of the common eland accompanied by meiotic chromatin compaction has greater implications in the reduction in the number of DSBs in leptonema than in the decrease of MLH1 foci number in pachynema.
Centric Fusions from Primary Cell Culture of Calf Kidney Applied to Chromosomal Evolution, Conservation and Speciation in the Bovidae Family
TLDR
The results suggest that evolutionary processes show a decrease in chromosome number from 2n=60 to 2n-48; on the other hand, acrocentric chromosomes tend to form (sub) metacentric chromosomes by chromosome fusion; however, with constant NAA specified for each family of mammals, NAA is a distinctive marker for detection of the mammalian positions of classification.

Cryptic chromosomal variation in suni Neotragus moschatus (Artiodactyla, Bovidae)
TLDR
Chromosomal variation among captive-born specimens and evidence of higher perinatal mortality in supposed hybrid cytotypes suggest that these two subspecies should be managed as separate populations, particularly with regard to captive breeding, reintroductions, and animal translocations.
Chromosomal evolution in gazelles.
TLDR
A phylogenetic reconstruction confirms most of the taxonomic relationships obtained by morphological analyses for this group of species, and the main novelties are the proximity of G. rufifrons and G. thomsoni and the inclusion of Antilope cervicapra in the gazelle group.
Chromosomal evolution in duiker antelope (Cephalophinae: Bovidae): karyotype comparisons, fluorescence in situ hybridization, and rampant X chromosome variation.
TLDR
Fluorescence in situ hybridization and conventional banding techniques were used to identify patterns of similarity among the genomes of six species of antelope, subfamily Cephalophinae, and revealed two euchromatic pericentric inversions which had occurred since their common ancestry.
The C-, G-, and R-banded karyotype of the scimitar-horned oryx (Oryx dammah).
TLDR
Karyotypes of five males and one female scimitar-horned oryx (Oryx dammah) were prepared using lymphocyte and skin cells, revealing a high level of homoeology except for chromosomes 9, 14, 21, Y, and X.
Cytogenetic aspects of phylogeny in the Bovidae. II. C-banding.
TLDR
The conservation of banding patterns in chromosome arms strongly indicates that Robertsonian translocation type rearrangements have provided the major source of interspecies karyotype differences, with inversions and reciprocal and tandem translocations providing relatively minor contributions.
Cytogenetic aspects of phylogeny in the Bovidae. I. G-banding.
TLDR
The conservation of banding patterns in chromosome arms strongly indicates that Robertsonian translocation type rearrangements have provided the major source of interspecies karyotype differences, with inversions and reciprocal and tandem translocations providing relatively minor contributions.
The karyotype of the addax and its comparison with karyotypes of other species of Hippotraginae antelopes.
TLDR
The comparison of banding patterns of chromosomes in addax and four other species of the subfamily Hippotraginae reveals several common features and a high degree of homoeology with caprine and bovine karyotypes.
Speciation by monobrachial centric fusions.
  • R. Baker, J. Bickham
  • Biology, Medicine

  • 1986
TLDR
Speciation mediated by centric fusions is a peripatric speciation model that does not postulate populational phenomena atypical of those characteristic of most mammals.
Chromosome conservation in the Bovidae.
TLDR
The chromosomes of 12 bovid species were harvested from fibroblast cultures after incorporation of bromodeoxyuridine into early replicating DNA and the commonness of monobrachially homologous biarmed chromosomes among some bovids suggested that reproductive isolation and speciation in some instances might have resulted from centric fusion events.
Cytogenetic aspects of phylogeny in the Bovidae. II. C-banding.
TLDR
Some evidence was found for a reduction in the amount of centromeric heterochromatin in bi-armed relative to acrocentric autosomes, and these findings are discussed in relation to karyotype evolution in the Bovidae.
