Chromosomal Mechanisms in the Evolution of Chiropteran Karyotype Chromosomal Tables of Chiroptera

Abstract

Chromosomal mechanisms involved in the evolution of the karyotype were examined in Chiroptera. In particular the Robertsonian process of centric fusion-fission was thoroughly studied. On the basis of karyological and morphological observations, the Authors aim to demonstrate that the Robertsonian change does not proceed in a single direction; it just provides a cytological basis for the onset of a genetic barrier. The importance of other chromosomal changes in the karyotypic evolution of Chiroptera has also been pointed out. A complete table of karyological data in Chiroptera is provided.
