Abstract: Chromosomal rearrangements such as fusions and fissions play an important role in promoting and maintaining speciation. To study these phenomena, genome architecture of three cryptic species of Leptidea wood white butterflies was investigated by means of standard and molecular cytogenetics. High variability in chromosome number and localization of cytogenetic markers was revealed, suggesting dynamic karyotype evolution in these species. Moreover, unique sex-determination system with 3-4 W chromosomes and 3-4 Z was found, possibly playing a role in the speciation process as well.
