Q-band comparisons were made among representative species of the four genera of the tribe Bovini (Bos, Bison, Bubalus, Syncerus) as well as to selected outgroup taxa representing the remaining two tribes of the subfamily Bovinae (nilgai, Boselaphini; eland, Tragelphini), the Bovidae subfamily Caprinae (domestic sheep) and the family Cervidae (sika deer and white- tailed deer). Extensive autosomal arm homologies were noted, but relatively few derivative character states were shared. Focus was… Expand
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
TLDR
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. Expand
Molecular Insights into X;BTA5 Chromosome Rearrangements in the Tribe Antilopini (Bovidae)
TLDR
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. Expand
Phylogenetic position of the saola (Pseudoryx nghetinhensis) inferred from cytogenetic analysis of eleven species of Bovidae
TLDR
The study revealed that nucleolar organizing regions (NORs) are phylogenetically informative and strongly suggests the saola’s placement within the subtribe Bubalina, which contrasts with Robertsonian rearrangements which are informative only at the generic level. Expand
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. Expand
Chromosome Rearrangements in the Tribe Antilopini ( Bovidae )
For a clade that includes Antilope, Gazella, Nanger and Eudorcas (Antilopinae), X;BTA5 translocation is a synapomorphy. Using a combination of fluorescence in situ hybridi zation (FISH) probes andExpand
Karyotype relationships among selected deer species and cattle revealed by bovine FISH probes
TLDR
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. Expand
Nanger, Eudorcas, Gazella, and Antilope form a well-supported chromosomal clade within Antilopini (Bovidae, Cetartiodactyla)
TLDR
The phylogenetic analysis of the chromosomal data supports monophyly of Nanger and Eudorcas and suggests an affiliation between A. cervicapra and some of the Gazella species, and renders Gazella paraphyletic and emphasizes a closer relationship between Antilope and Gazella than what has previously been considered. Expand
Molecular cytogenetic insights to the phylogenetic affinities of the giraffe (Giraffa camelopardalis) and pronghorn (Antilocapra americana)
TLDR
Analysis of cenDNA shows that unlike the pronghorn, the centromeres of the giraffe are probably organized in a more complex fashion comprising different repetitive sequences specific to single chromosomal pairs or groups of chromosomes. Expand
Evolution of satellite DNA sequences in two tribes of Bovidae: A cautionary tale
TLDR
Two clones, Bt1 from Bos taurus and Om1 from Ovis orientalis musimon, were used as probes for hybridization on genomic DNA and on metaphase chromosomes in members of Bovini and Caprini tribes and showed almost 100% homology with a bacterial sequence reported in Helicobacter pylori. Expand
Physical organization of the 1.709 satellite IV DNA family in Bovini and Tragelaphini tribes of the Bovidae: sequence and chromosomal evolution
TLDR
The data suggest that the sequences on the sex chromosomes and the autosomes evolve as relatively independent groups, with the repetitive sequences suggesting that Bovini autosomes and the Tragelaphini sex chromosomes represent the more primitive chromosome forms. Expand

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

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. Expand

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.

Chromosome conservation among the advanced pecorans and determination of the primitive bovid karyotype.
TLDR
Comparative cytogenetic data among the advanced pecorans strongly suggest that the 2n = 60, NAA = 58 karyotype found in several species of the tribe Bovini is probably near the primitive condition for the Bovidae. Expand
A Karyotypic Analysis of Nilgai, Boselaphus Tragocamelus (Artiodactyla: Bovidae)
TLDR
Comparisons with cattle identified extensive monobrachial homologies with some noteworthy exceptions and chromosomal banding and FISH were used to determine that autosome 14 has been fused to the ancestral X and Y of nilgai to form compound neo-X and -Y chromosomes. Expand
Chromosomal evolution in bovids: a comparison of cattle, sheep and goat G- and R-banded chromosomes and cytogenetic divergences among cattle, goat and river buffalo sex chromosomes
TLDR
A large number of banding homologies among the autosomes of the three species were revealed and some ambiguities in arranging some of their small disputed acrocentrics were resolved by direct and indirect comparisons with some bovid marker chromosomes. Expand
Evolutionary histories of highly repeated DNA families among the artiodactyla (mammalia)
TLDR
Six highly repeated DNA families were analyzed using Southern blotting and fluorescence in situ hybridization in a comparative study of 46 species of artiodactyls belonging to seven of the eight extant taxonomic families, supporting the monophyly of the infraorder Pecora, an inability to resolve any interrelationships among the other tribes of bovids, and a lack of molecular variation among two morphologically and ecologically distinct subspecies of African buffaloes.

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

Chromosome studies in the mammalian subfamily Antilopinae
TLDR
A taxonomy has been constructed which differs most markedly from the classical taxonomy in two aspects: the blackbuck, Antilope cervicapra, shows a strong karyotypic affinity to gazelles of the subgenus Nanger; Thomson's gazelle, Gazella thomsoni, lacks the numerous Robertsonian fusions and the X-autosome translocation common to other members of Gazella studied to date. Expand
Chromosomal evolution in Cervidae.
TLDR
While the karyotypes are conserved within the subfamilies Cervinae and Odocoileinae; the subfamily Muntiacinae appears to be the most chromosomally diversified group. Expand
