The role of chromosome change. Submetacentric Cavia tschudii chromosomes Cts, first column at the left that originate the subtelocentric Cavia porcellus chromosomes Cpo, last column at the right: Cytogenetic and Cell Genetics The differences in the number of AgNOR bands found between the two Cavia species stchudii here and among the individuals in each of them, confirmed the tendency to variability in NOR expression usually tsvhudii for mammals.
Published online Jul In other projects Wikispecies.
Comparison of the G-banded karyotypes of the two Cavia species included in this study revealed that most of the autosomal pairs and the X chromosomes showed total G band correspondence, suggesting that these chromosomes constitute large syntenic blocks present in the common ancestor of both species and conserved over time.
Walker1 Miguel A. Redford 15 May Rough simulation of the changes associated with the occurrence of pericentric inversions in Cavia tschudii chromosomes.
Bennett inwho termed them Cavia cutleri. University of California Publications in Zoology The boliviensis group of Akodon Rodentia: It has been proposed that this variability would depend mainly on the specific metabolic demands of cells and individuals Mikelsaar et al. Cavia tschudii Fitzinger, . Journal List Comp Cytogenet v. Abstract We report the first record of the genus Cavia and the species Cavia tschudii Rodentia, Caviidae in Catamarca province, northwestern Argentina, which represents a range extension of about km southward for the species.
Five chromosomal pairs bearing NOR at the short arm telomeres were found by Zenzes et al.

Capybara Hydrochoerus hydrochaeris Lesser Capybara Hydrochoerus isthmius. We report the first record of the genus Cavia and the species Cavia tschudii Rodentia, Caviidae in Catamarca province, northwestern Argentina, which represents a range extension of about km southward for the species.
Journal of Genetics Both species showed 64 chromosomes of similar morphology, although C.
Specifically, the fertility of the heterozygotes for the pericentric inversions described here should be further investigated to evaluate the contribution of those chromosomal changes to the divergence of the two Cavia species. It is even more difficult to obtain descendants from crosses between different chromosomal races or species in the laboratory Walker et al. Metaphase cells were G-banded and C-banded by the methods described by Chiarelli et al.

The role of the chromosomal and genomic differences in the divergence of these two Cavia species is discussed. Rock Cavy Kerodon rupestris Acrobatic cavy Kerodon acrobata. International Union for Conservation of Nature. Xavia polymorphism for chromosome 1 short arms detected previously for Cavia cobaya Pallas,a synonym of Cavia porcellusOhno et al.
Moreover, when we examined all the 3. Eds The quintessential naturalist: Specifically, the heterozygotes for the pericentric inversions would have decreased their fertility since their gametes would be unbalanced as a result of crossing-over in the inverted segment Coyne et al.
