Chromosome banding pattern homology and its phlogenetic implications in the bat genera Carollia and Choeroniscus.
A comparison of the chromosome banding patterns of the mitotic chromosomes of three species of bats of the genus Carollia and Choeroniscus intermedius revealed considerable banding pattern homology between the Carollia species but not between Carollia and Choeroniscus. The G-band patterns of the chromosomes of the Carollia species were similar, but the C-band (heterochromatin) pattern of C. castanea (Peru) lacked much of the heterochromatin common to the other two species. C. castanea also lacked the X-autosome translocation possessed by the other two species. A system for denoting such sex-chromosome translocations is presented rather than presenting the chromosomes involved as multiple sex chromosomes. The G- and C-banding patterns of Choeroniscus intermedius did not resemble those of Carollia, and the placement of these bat genera into different subfamilies is supported.
