The Chinese hamster (Cricetulus griseus) and striped hamster (Cricetulus barabensis) are very closely related species with similar karyotypes. The karyotypes differ from each other by one Robertsonian rearrangement and X-chromosome morphology. The level of the tandem repeat (TR) sequences’ evolutional variability is high. The aim of the current wor...

Constitutive heterochromatin is the most mysterious part of the eukaryotic genome. It forms vital chromosome regions such as the centromeric and the pericentromeric ones. The main component of heterochromatic regions are tandem repeats (TR), and their specific organization complicates assembly, annotation, and mapping of these regions. Unannotated...

... According to FISH data (Romanenko et al., 2007), as well as data on the variability of structural heterochromatin (Vakurin et al., 2014), significant differences in the chromosome structure of all described chromosomal forms in the group C. barabensis s. l. and the error of classifying them as a single species were demonstrated. New information about the absence of intensive hybridization in the contact zones of C. barabensis and C. pseudogriseus and differences in the location of nDNA repeats in the chromosomes of C. barabensis and C. griseus confirm the species status of these forms (Poplavskaya et al., 2012;Ivanova et al., 2022). ...
