The very long telomeres in Sorex granarius (Soricidae, Eulipothyphla) contain ribosomal DNA.

Two closely related shrew species, Sorex granarius and Sorex araneus, in which Robertsonian rearrangements have played a primary role in karyotype evolution, present very distinct telomere length patterns. S. granarius displays hyperlong telomeres specifically associated with the short arms of acrocentrics, whereas telomere lengths in S.

Unusual distribution pattern of telomeric repeats in the shrews Sorex araneus and Sorex granarius.

Sorex araneus and Sorex granarius are sibling species within the Sorex araneus group with karyotypes composed of almost identical chromosome arms. S. granarius has a largely acrocentric karyotype, while, in S.

Zoo-FISH with region-specific paints for mink chromosome 5q: delineation of inter- and intrachromosomal rearrangements in human, pig, and fox.

Comparison of evolutionarily conserved mammalian chromosomes homologous to human chromosome 17, performed with microdissected painting probes, revealed rearrangements inside these chromosomes in mink and pig and a disruption of this conserved region in the fox. Detection of a homologous region on an Iberian shrew chromosome showed the efficiency of microdissected painting probes for delineation of homologous chromosome regions in species belonging to orders that diverged at least 100 million years ago.
