Abstract
Banded karyotypes were compared in 3 species of lemurs,Lemur catta (2n=56),L. f. fulvus (2n=60) andL. mongoz (2n=60). The karyotypes of the latter 2 species were indistinguishable from each other in both Q-band and G-band patterns, except thatL. mongoz had an unusually large Y chromosome. The karyotypic differences betweenL. catta and the other 2 species were mainly explained by centric fusions (or fissions) and pericentric inversions. Contrary to the general similarity in Q-band and G-band patterns, the C-band patterns were highly variable among the 3 species. All chromosomes ofL. fulvus had a distinctive C-band in the centromeric region, whileL. mongoz had only a few chromosomes with an apparent C-band.L. catta was remarkable by showing interstitial and terminal C-bands in some elements, in addition to the centromeric band which was observed in about 20 pairs.
