Karyotypes of two whiptail lizards (Cnemidophorus) from Arroyo del Macho. A. Diploid unisexual C. tesselatus, AMNH R­146638 (2n = 46). This unisexual taxon is a clone with its ultimate ancestor being an F1 hybrid between C. tigris marmoratus (haploid complement of chromosomes in the upper two rows) X C. gularis septemvittatus (haploid complement in the lower two rows). Large arrow points to the centromere of the X­chromosome ultimately inherited from C. tigris marmoratus; this chromosome apparently had undergone centric fission into two telocentric chromosomes in the other karyotypic clone of C. tesselatus found at the same locality (2n = 47). B. Triploid hybrid between C. tesselatus X C. tigris marmoratus (male), AMNH R­146690 (3n = 69). The four rows of chromosomes above the scale bar represent the two haploid complements inherited from C. tigris marmoratus, whereas the lower two rows represent the single haploid complement from C. gularis septemvittatus. The Ychromosome was inherited from the most recent backcross hybridization between C. tesselatus and C. tigris marmoratus. Bar represents 10 µm. Small arrows in both A and B illustrate distinctive secondary constrictions (nucleolar organizer regions) from C. gularis septemvittatus.	Fig. 9.
