On mammals collected by Sr. Carnegie Institution of Washington Publications The four submetacentric chromosomes present only in the Cavia tschudii karyotype showed partial G band correspondence with four Cavia porcellus subtelocentric chromosomes Fig. Chromosomes numbered according to original karyotype descriptions see Fig.

C bands The chromosomal distribution of the C bands was similar in the karyotypes of the two species, being located preferentially in the centromeres and the short arms of the chromosomes Fig. Article Tools How to cite item.

Montane guinea pig

This page was last edited on 15 Februaryat The montane guinea pig is native to the high Andes in South America.

To investigate the genetic divergence between the tchudii and domestic species of guinea pigs from a cytogenetic perspective, we characterized and compared the C, G and AgNOR banded karyotypes of molecularly identified Cavia tschudii and Tschudoi porcellus Linnaeus, specimens for the first time.

Cavia tschudii Fitzinger, is a wild guinea pig species living in South America that according to the analysis of mitochondrial genes is the closest wild form of the domestic guinea pig.

Reproduction of wild mammal species caviaa captivity is a difficult and not always successful task. The nucleolar chromosomes of both species were tentatively identified according to their size and morphology.

The role of the chromosomal and genomic differences in the divergence of these two Cavia species is discussed.

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 wild mammals of Jujuy province, Argentina: Based on these molecular results and on the analysis of mummified guinea pig remains found in archeological sites, Spotorno et al.

The montane twchudii pig is the likely ancestor of Cavia porcellusthe cavy or domestic guinea pig. Journal of Zoological Systematics and Evolutionary Research 48 4: Capybara Hydrochoerus hydrochaeris Lesser Capybara Hydrochoerus isthmius.

Moreover, when we examined all the 3. Revista Chilena de Historia Natural Range extension of Cavia tschudii Fitzinger, Mammalia: 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 hschudii constitute large syntenic blocks present in the common ancestor of both species and conserved over time.

National Center for Biotechnology InformationU.

Most of the two species chromosomes showed total G band correspondence, suggesting that they probably represent large syntenic blocks conserved over time. However, the amount of constitutive heterochromatin was appreciably greater in Cavia tschudii than in Cavia porcellusspreading over most of the short arms in several subtelocentric chromosomes Fig.

Only the Y chromosomes and two autosomal pairs Cavia tschudii chromosomes 12, 13 and Cavia porcellus chromosomes 14, 18 were unique of each species karyotype Table 1.

Cavia tschudii – Wikispecies

To investigate the genetic divergence between the wild and domestic species of guinea pigs from a cytogenetic perspective, we characterized and compared the C, G and Cvia banded karyotypes of molecularly identified Cavia tschudii and Cavia porcellus Linnaeus, specimens for the first time.

Journal of Mammalogy Archives of Biology Redford 15 May Cavia tschudii Fitzinger, Mammalia: Support Center Support Center. 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.
