Comparative cytogenetic analysis with differential staining in three species of Liolaemus (Squamata, Tropiduridae)

Comparative cytogenetic studies based on conventional staining, CBG-banding, RBG-banding, and Ag-NOR staining, were performed on three species of Liolaemus: L. occipitalis, L. lutzae and L. wiegmannii. The three species have 2n = 34, with closely similar karyotypes and an XX:XY mechanism of sex determination. The cytogenetic analysis allowed the detection of differences among the macrochromosomes of the three species and some other features characteristic of each species. The karyotype of L. occipitalis and the banding patterns of L. lutzae and L. wiegmannii have not been reported previously.
