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…

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
- BiologyChromosome Research
- 2008
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.
Molecular Insights into X;BTA5 Chromosome Rearrangements in the Tribe Antilopini (Bovidae)
- BiologyCytogenetic and Genome Research
- 2012
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.
Phylogenetic position of the saola (Pseudoryx nghetinhensis) inferred from cytogenetic analysis of eleven species of Bovidae
- BiologyCytogenetic and Genome Research
- 2008
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.

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

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.
Evolution of satellite DNA sequences in two tribes of Bovidae: A cautionary tale
- Biology, MedicineGenetics and molecular biology
- 2015
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.
Physical organization of the 1.709 satellite IV DNA family in Bovini and Tragelaphini tribes of the Bovidae: sequence and chromosomal evolution
- BiologyCytogenetic and Genome Research

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.
Examination of hemiplasy, homoplasy and phylogenetic discordance in chromosomal evolution of the Bovidae.
- BiologySystematic biology

It is concluded that the most probable interpretation for these data is that genuine karyotypic homoplasy predominates, but that hemiplasy (and/or introgression) is a realistic hypothesis for the observed patterns of several shared characters in Bovidae.
Cross-species chromosome painting among camel, cattle, pig and human: further insights into the putative Cetartiodactyla ancestral karyotype

A Cetartiodactyla ancestral karyotype is proposed and a genome-wide comparative chromosome map of human/pig/cattle is constructed to facilitate the positional cloning of genes by aiding the cross-species transfer of mapping information.

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.

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.

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.

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.

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.

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.

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.
