Karyotype Evolution and Formation of Mammals Diversity
A.V. Polyakov, M.S. Bukina, P.M. Borodin
Abstract
Mechanisms and history of formation of chromosome variations of modern species of small mammals in Palearctic are discussed on the example of the common shrew (Sorex araneus L.), a species characterized by a wide range of karyotypic variability. Fragmentation of the species areas during the last glaciation and drift of allelic and chromosomal variants apparently played a leading role in the formation of the species structures. structures.
