Karyotypes of Three Species of the Gennus Draco (Agamidae: Lacertilia) from Sabah, Malaysia

Abstract

The first karyological survey was made for D. cornutus, D. haematopogon, and D. quinquefasciatus by bone marrow cell preparations. Despite the distinct in-terspecific diversification in external characteristics, the three species have identical karyotypes: somatic chromosomes, 2n=34, consisting of six pairs of large metaccen-tric, two pairs of small metacentric, and nine pairs of small acrocentric elements. The results seem to indicate the relative chromosomal conservativeness of the genus.
