Reciprocal chromosome painting among human, aardvark, and elephant (superorder Afrotheria) reveals the likely eutherian ancestral karyotype

TL;DR: The comparative chromosome maps presented between human and these Afrotherian species provide further insight into mammalian genome organization and comparative genomic data for theAfrotheria, one of the four major evolutionary clades postulated for the Eutheria.
Journal ArticleDOI

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

TL;DR: 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.
Journal ArticleDOI

Chromosome painting refines the history of genome evolution in hares and rabbits (order Lagomorpha)

TL;DR: The molecular cytogenetic data allow for a refinement of the structural changes that have shaped genome evolution in this group of mammals and underscore the rapid radiation of the Leporidae suggested by mitochondrial DNA sequence data.
Journal ArticleDOI

Chromosomal evolution in duiker antelope (Cephalophinae: Bovidae): karyotype comparisons, fluorescence in situ hybridization, and rampant X chromosome variation.

TL;DR: 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.
Journal ArticleDOI

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

TL;DR: 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.
