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.
Received Mar 13; Accepted Jun Annals and Magazine of Natural Historyser. The montane guinea pig is the likely ancestor of Cavia porcellusthe cavy or domestic guinea pig. Submetacentric Cavia tschudii chromosomes Cts, first column at the left that originate the subtelocentric Cavia porcellus chromosomes Cpo, last column at the right: By contrast, the crosses between Cavia porcellus and Cavia aperea sensu Erxleben, Pictet and FerreroRood and between Cavia porcellus and Cavia cutleri Tschudi, sensu Bennet, Castle produced hybrids which were caviw in both sexes.
Redford 15 May International Union for Conservation of Nature. The differences in morphology and the partial G band correspondences detected between four chromosomal pairs of these two species, suggest that the four submetacentric chromosomes present only in the Cavia tschudii karyotype would have suffered pericentric inversions originating the four subtelocentric chromosomes of Cavia porcellus Fig.

Montane guinea pig Conservation status. If the analysis of the crosses realized between chromosomal races of Mus and Sorex rodents Hauffe and SearleCastiglia and CapannaFranchini et al.
On mammals collected by Sr. In Argentina it lives in burrows with several entrances.
Mammal species of the world: The differences in the number of AgNOR bands found between the two Cavia species analyzed here and among the individuals in each of them, confirmed the tendency to variability in NOR expression usually described for mammals. Eds High altitude tropical biogeography. Tschudiu Natural Corrientes 5: Cts chromosomes are at the left and Cpo at the right of each chromosomal group.
Cytogenetic and Genome Research Carnegie Institution of Washington Publications The cranial and dental remains were recovered from an owl pellet sample found in eastern slopes of the Ambato range, at m elevation, in a highland grasslands-Chaco Serrano ecotone.

Cavia porcellus would be the domestic successor of Cavia tschudii from which it would have originated more than and possibly years ago Wing by a process of domestication and artificial selection in the Cavia tschudii populations which inhabit southern Peru and northern Chile Spotorno et tschudui.
Molecular systematics, taxonomy, and biogeography of the genus Cavia Rodentia: Introduction Cavia tschudii Fitzinger, is a wild species of guinea pig RodentiaCaviidae which inhabits northern Chile, southern Peru and Bolivia and northwestern Argentina WeirWoods and Kilpatrick The montane guinea pig is native to the high Andes in South America. This article has been cited by other articles in PMC.
The analysis of some AgNOR banded metaphases per species indicated that the number of AgNOR bands was different between the two species and also among the individuals. The nucleolar chromosomes of both species were tentatively identified according to their size and morphology.
Article Tools How to cite item. Range extension of Cavia tschudii Fitzinger, Mammalia: Differences in the C bands size and the mean number of AgNOR bands between the karyotypes of the two species were detected.
Symposia of the Zoological Society of London European Journal of Morphology Walker1 Miguel A. Five chromosomal pairs bearing NOR at the short arm telomeres were found by Zenzes et al. Nevertheless, it has been demonstrated recently that the fertility of the inversion carriers is not always reduced Muss and Schwanitz Both Y chromosomes were completely heterochromatic, being larger the Y chromosome of Cavia tschudii than the Cavia porcellus one Fig. Published online Jul An accurate identification of the Cavia porcellus and Cavia tschudii nucleolar chromosomes described here would require the use of a similar double-staining procedure to allow the comparisons with other descriptions.
