The karyology was studied in nine species of Antilopinae and evaluated with regard to cytotaxonomic relations within the subfamily. Karyotypes of three of these species were previously undescribed. Chromosomes were examined by conventional staining methods, G-, C-, and T-banding techniques, and by autoradiography. Evolutionary differentiation of karyotypes in this group is characterized by extensive Robertsonian fusions and a particular translocation between the X chromosome and an autosome… 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
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
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
Examination of hemiplasy, homoplasy and phylogenetic discordance in chromosomal evolution of the Bovidae.
TLDR
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. Expand
A Molecular Cytogenetic Analysis of the Tribe Bovini (Artiodactyla: Bovidae: Bovinae) with an Emphasis on Sex Shromosome Morphology and NOR Distribution
TLDR
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. Expand
The chromosomes of Gazella bennetti and Gazella saudiya
TLDR
Seven individuals of captive Gazella bennetti were found to have chromosomal complements of 2n = 49-52, and seven captive G. saudiya had complements that revealed variation in diploid number was the result of an autosome-to-X chromosome translocation and four independent Robertsonian translocations. Expand
A karyotypic analysis of the lesser Malay chevrotain,Tragulus javanicus (Artiodactyla: Tragulidae)
TLDR
Outgroup comparisons indicate that the acrocentric condition of cattle chromosome 19 has been derived by inversion, and molecular cytogenetic analyses indicate complete conservation of synteny among mouse deer chromosome 15, domestic cattle chromosomes 19, domestic pig chromosome 12 and human chromosome 17.

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. 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.

Chromosomes ofDamaliscus (Artiodactyla, Bovidae): Simple and complex centric fusion rearrangements
G- and C-banded karyotypes ofDamaliscus hunteri, D. lunatus andD. pygargus were compared using the standard karyotype ofBos taurus. Chromosomal complements were 2n=36 inD. lunatus jimela, 2n=38 inD.Expand

Comparative chromosome studies in Cetacea.
TLDR
The pronounced karyotypic agreement between the odontocetes and mysticetes, both in general chromosome morphology and in C-band pattern, is incompatible with the theory of a diphyletic origin of the OdontocETi and Mysticeti. 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

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

TLDR
The examination of the possible homology or heterology by breeding procedures revealed the surprising fact that independence, partial or heterobrachial homology of the metacentric chromosomes prevail among mice from different geographical areas. Expand

Placental anatomy and chromosomes from leucocyte cultures of opposite-sexed white-tailed deer twins were investigated with particular interest as to the possible existence of chimerism, and freemartin effects as a cause of antler growth in does. Expand
