... karyotyped, showing high levels of diploid number variation, which allowed clustering species in chromosome number groups: 2n = 24 ( Aplastodiscus perviridis group), 2n = 22 ( Aplastodiscus albofrenatus group), 2n = 20, and 2n = 18 (both within Aplastodiscus albosignatus group). This study aims to report...

...Tiago M. Degrandi; Suziane A. Barcellos; Alice L. Costa; Analía D.V. Garnero; Iris Hass; Ricardo J. Gunski Bird chromosomes, which have been investigated scientifically for more than a century, present a number of unique features. In general, bird karyotypes have a high diploid number (2n...

... to characterize the genomes. In both species, inverted DAPI karyotypes showed the same diploid number, 2n = 46, and hybridization of the (TTAGGG) n probe revealed interstitial telomeric sequences (ITSs) at the centromeres of almost all bi-armed chromosomes. FISH with the rDNA probe localized nucleolus organizer...

Vicari The karyotypes of the family Parodontidae consist of 2n = 54 chromosomes. The main chromosomal evolutionary changes...

.... Knowledge of the karyotypes can facilitate genome assembly and further our understanding of sex chromosome evolution in Lepidoptera. Here, we describe the karyotypes of the Glanville fritillary Melitaea cinxia (n = 31), the monarch Danaus plexippus (n = 30), and the African queen D. chrysippus (2n = 60...

... of the eutherian tree. The use of modern cytogenetic techniques in some species of Xenarthra has provided important insights into the karyotypic evolution of mammals. Nevertheless, chromosome analyses in the group are still restricted, with only a few individuals of each species studied and karyotype descriptions...

... , and A. crassiuscula are distributed in Uruguay and popularly known as ‘marcelas’. In order to characterize them, we performed chromosome counts, compared the karyotypes, mapped the 5S and 45S rDNA sites by fluorescent in situ hybridization, and estimated their DNA content. All species were diploid with 2n = 28...
