| Abstract: | A comparative analysis of G-banded karyotypes was performed for seven species of Chiroptera, representing two families (Phyllostomidae
and Molossidae). Despite the differences in diploid and fundamental numbers, extensive homologies between six karyotypes were
identified: A . planirostris, P. lineatus, S. lilium, G. soricina, P. hastatus (Phyllostomidae) and M. rufus (Molossidae). Robertsonian rearrangements and pericentric inversions account for the differences between the karyotypes of
phyllostomid and molossid species. The homologies and rearrangements observed reinforce the monophiletic origin of phyllostomids
and the inclusion of species in different subfamilies. In situ hybridization with genomic DNA revealed considerable conservation of the karyotypes, including C. perspicillata, that did not show G-band homologies with the other species analyzed. For the first time, chromosomal evidence is presented
of a common origin for Phyllostomidae and Molossidae. |
