... regions. Recently, populations of Ctenomys have been found in the Midwest and northern Brazil, with two new lineages named C. sp. “xingu” and C. sp. “central.” Methods: This work combines classical cytogenetic and molecular analyses to provide new chromosomal information on the boliviensis group...

... to the occurrence of mimicry. The objective of this work was to cytogenetically characterize 3 very similar species of the genus Alagoasa ( A. pantina , A.areata , and A.scissa ). We used classical and molecular cytogenetic as well as molecular genetic techniques. All 3 species showed a diploid chromosome number...

... the development of the first comprehensive whole-genome integrated cytogenetic map for the alpaca using fluorescence in situ hybridization (FISH) and CHORI-246 BAC library clones. The map is comprised of 230 linearly ordered markers distributed among all 36 alpaca autosomes and the sex chromosomes. For the first...

...K. Ocalewicz In fishes, as in other vertebrate species, the DNA component of the telomeres consists of the tandemly repeated TTAGGG motif. The length of the telomeric arrays in fishes ranges from 2 to 25 kb and shortens with age in some of the species. To date, chromosomal distribution...

...B. Dutrillaux; A.-M. Dutrillaux The karyotypes of 5 species of Dynastes, D. hercules, D. tityus, D. granti, D. satanas, and D. neptunus , and 2 subspecies of D. hercules are compared with those of 6 other selected Dynastinae species. In the 3 former species, there are 18 chromosomes, including neo...

...I.E. Jetybayev; A.G. Bugrov; T.V. Karamysheva; J.P.M. Camacho; N.B. Rubtsov Chromosome location of ribosomal DNA (rDNA) and telomeric repeats was analysed in mitotic chromosomes of 15 species of Gomphocerinae grasshoppers belonging to the tribes Arcypterini, Gomphocerini, Stenobothrini...

...F. Richard; B. Dutrillaux Lagomorpha (rabbits and pikas) and Sciuromorpha (squirrels) are grouped in the Glires superorder. Their chromosome diversification, since their separation from the eutherian mammalian common ancestor, was characterized by a low rate of chromosome rearrangements...

... chromosome fragments. Remnants of the irradiated chromosomes had different sizes, and their number varied intraindividually from 1 to 15. To efficiently pass through the series of the cell divisions, such chromosome fragments must have had functional kinetochores. Distribution patterns of the telomeric...

...A.-M. Dutrillaux; B. Dutrillaux The aim of this study was the identification of the ancestral location of the nucleolus organizer region (NOR) in the Scarabaeoidea superfamily, and its evolutive trends in the karyotypes. For this purpose, the mitotic and meiotic chromosomes at pachynema of 82...

... genomic in situ hybridization (GISH) to identify parental chromosomes of P.lessonae and P.ridibundus in diploid P . esculentus karyotypes (2n = 26). GISH probes were made by fluorochrome labeling of total genomic DNA extracted from the sexual progenitors. The labeled probe from one species was hybridized...

...A. Ronceret; W.P. Pawlowski Early stages of meiotic prophase are characterized by complex and dramatic chromosome dynamics. Chromosome behavior during this period is associated with several critical meiotic processes that take place at the molecular level, such as recombination and homologous...

...T. Osada; N. Kakazu; M. Watanabe; H. Yamane; T. Yagi Spectral karyotyping (SKY) was used to assess the chromosomal constitution of embryos generated by nuclear transfer (NT) of neuronal nuclei (N-NT) or cumulus cell nuclei (C-NT) into oocytes and of their embryonic stem cell derivatives (ntES cells...

...A.M. Dutrillaux; B. Dutrillaux The karyotype of Macraspis tristis Laporte is described. It is composed of 18 chromosomes. C-band positive heterochromatin is very abundant and is located at centromeric regions and, for some chromosomes, at telomeric regions. There is a high inter-individual...
