'Hidden' differences of chromosome organization become visible

Why do different species have dissimilar sets of chromosomes? Why do the differentiated species often conserve apparently identical chromosome complements? Furthermore, why, while chromosome rearrangements can considerably change the course of species evolution, do certain variation among individuals and populations of some species persists indefinitely? Such questions motivate researchers to compare chromosomes in closely related species. To understand the nature of chromosome changes in the voles Microtus savii, researchers launched a molecular cytogenetic study.
