Chromosomal homologies have been established between cattle (Bos taurus, 2n = 60) and eight species of spiral-horned antelope, Tribe Tragelaphini: Nyala (Tragelaphus angasii, 2n = 55♂/56♀), Lesser kudu (T. imberbis, 2n = 38♂,♀), Bongo (T. eurycerus, 2n = 33♂/34♀), Bushbuck (T. scriptus, 2n = 33♂/34♀), Greater kudu (T. strepsiceros, 2n = 31♂/32♀), Sitatunga (T. spekei, 2n = 30♂,♀) Derby eland (Taurotragus derbianus 2n = 31♂/32♀) and Common eland (T. oryx 2n = 31♂/32♀).

Chromosome evolution in the subtribe Bovina (Mammalia, Bovidae): The karyotype of the Cambodian banteng (Bos javanicus birmanicus) suggests that Robertsonian translocations are related to interspecific hybridization

It is suggested that Robertsonian translocations have been fixed in the common ancestor of Cambodian banteng as a consequence of hybridization with the kouprey (Bos sauveli) during the Pleistocene epoch.

Chromosome Homologies between Tsessebe (Damaliscus lunatus) and Chinese muntjac (Muntiacus reevesi) Facilitate Tracing the Evolutionary History of Damaliscus (Bovidae, Antilopinae, Alcelaphini)

The phylogenomic relationships of 3 species reflected by specific chromosomal rearrangements were consistent with published phylogenies based on morphology, suggesting that chromosomal upheavals have played an important role in speciation within the Alcelaphini, and that karyotype characters are valuable phylogenetic markers in this group.

Chromosome Rearrangements in the Tribe Antilopini ( Bovidae )

A markedly smaller centromere in the BTA5 (Y2) unfused chromosomes in males in the XY1Y2 determining system in comparison with other acrocentrics is discussed.

Molecular Insights into X;BTA5 Chromosome Rearrangements in the Tribe Antilopini (Bovidae)

The present study provides the first insight into the X;BTA5 architecture which differs in the species under study, and emphasizes the importance of chromosomal rearrangement verification, particularly, if they are used for phylogenetic analysis.

Multi-locus phylogeny of the tribe Tragelaphini (Mammalia, Bovidae) and species delimitation in bushbuck: Evidence for chromosomal speciation mediated by interspecific hybridization.

A paradox revealed: karyotype evolution in the four-horned antelope occurs by tandem fusion (Mammalia, Bovidae, Tetracerus quadricornis)

It is concluded that the attendant result of each fusion is an enlarged acrocentric fusion element comprising a single functional centromere and two terminal telomeres that, collectively, led to a reduction of the 2n’= 58 bovid ancestral ac rocentric chromosomal complement to the 2 n’s detected in the four-horned antelope.

Karyotype relationships among selected deer species and cattle revealed by bovine FISH probes

This work reports chromosomal homologies between cattle and nine cervid species using a combination of whole chromosome and region-specific paints and BAC clones derived from cattle, and characterised four repetitive sequences organized in heterochromatic blocks on sex chromosomes of the reindeer.

A Comparative Study of Pygmy Hippopotamus (Choeropsis liberiensis) Karyotype by Cross-Species Chromosome Painting

It is demonstrated that cattle probes are useful not only in comparative studies within Ruminantia, but also in more phylogenetically distant Artiodactyla species.

Cytotypes of Kirk’s Dik-Dik (Madoqua kirkii,Bovidae) Show Multiple Tandem Fusions

The analyses show centromeric sequences at two of the six tandem fusion junctions of M. kirkii, and the findings in the context of chromosomal evolution in these antelopes are discussed.

Analysis of the Robertsonian (1;29) fusion in Bovinae reveals a common mechanism: insights into its clinical occurrence and chromosomal evolution

By analysing the reorganization of satDNAs in the centromeric regions of translocated chromosomes, it is shown that Rb fusions are multistep, complex rearrangements which entail the precise elimination and reorganizations of specific (peri)centromeric satDNA sequences.

A molecular cytogenetic analysis of X chromosome repatterning in the Bovidae: transpositions, inversions, and phylogenetic inference

A paucity of comparative mapping data precludes the assignment of the sequences contained in cattle Xp to either the presumed conserved (XCR) or the recently added (XAR) region of the eutherian X chromosome, and the reasons for the retention of these sequences as an evolutionarily conserved unit in the intrachromosomal restructuring of the bovid X across lineages remain enigmatic.

X chromosome evolution in the suni and eland antelope: detection of homologous regions by fluorescence in situ hybridization and G-banding.

It is shown that intrachromosomal rearrangements distinguish the X chromosomes of these species, and it is believed that this approach (combining conventional and molecular cytogenetic studies on the X chromosome) will prove useful for inferring phylogenetic relationships in the family Bovidae, particularly as more probes become available.

The chromosomes of 45 mongooses (Herpestinae) representing 5 genera and 12 species were studied mainly in tissue cultures of skin biopsies. Karyotypes and idiograms were constructed for the different…

A Molecular Cytogenetic Analysis of the Tribe Bovini (Artiodactyla: Bovidae: Bovinae) with an Emphasis on Sex Shromosome Morphology and NOR Distribution

Comparisons among representative species of the tribe Bovini and selected outgroup taxa indicate that a knowledge of the chromosomal distribution of NORs among the Bovidae will prove to be phylogenetically informative.

Cytochrome b phylogeny of the family bovidae: resolution within the alcelaphini, antilopini, neotragini, and tragelaphini.

All evidence suggests that the Alcelaphini form a monophyletic group; there was no support for the recognition of the Lichtenstein's hartebeest in a separate genus (Sigmoceros), and the acceptance of the previously suggested Al Celaphus is recommended for this species.

Chromosomal evolution in gazelles.

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.

Molecular and morphological phylogenies of ruminantia and the alternative position of the moschidae.

A Bayesian relaxed molecular clock approach based on the continuous autocorrelation of evolutionary rates along branches was applied to estimate the divergence ages between the major clades of ruminants, confirming the traditional view that separates Tragulina and Pecora.

Complex evolution of X and Y autosomal translocations in the giant mole-rat, Cryptomys mechowi (Bathyergidae)

The likely sequence of evolutionary events that has led to the contemporary composition of the C. mechowi sex chromosomes are discussed, and these are considered in the light of prevailing views on the genesis of sex chromosomes in mammals.

Cytogenetic aspects of phylogeny in the Bovidae. II. C-banding.

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.
