Right. Banding patterns of PGM2 that distinguish septentrionalis (SEP, genotype cc) from punctilinealis (PUN genotype dd), marmoratus (MAR, genotype dd), and aethiops (genotype dd, not illustrated).

Fig. 49. The contact region. Horizontal lines represent range of pure punctilinealis (coloration indices of 0–0.1; table 24), and vertical lines pure marmoratus (coloration indices of 0.8–1.0). Sites in between (2–5, 18, 19, 26, and 41–44) represent primarily hybrids (coloration indices of 0.11–0.79).

Fig. 52 in Hybridization Among Western Whiptail Lizards (Cnemidophorus Tigris) In Southwestern New Mexico: Population Genetics, Morphology, And Ecology In Three Contact Zones

Fig. 52. Differences in the tissue distribution of lactate dehydrogenase, a tetramer. Top (six lanes) LDH1 predominates in heart. Bottom (five lanes). Both LDH1 and LDH2 are active in liver and the banding patterns include numerous isozymes composed of subunits of both. Note the fivebanded patterns for LDH1 for heterozygous diploid C. neomexicanus (NEO) and a triploid hybrid (HYB) of neomexicanus × tigris. In the heart tissue, LDH1 genotype ab for neomexicanus, the isozymes approximate activities of 1:4:6:4:1. For the triploid hybrid with genotype aab, the faster migrating isozymes stain most intensely (activities approximate the theoretically expected ratio of 16:32:24:8:1). These patterns are consistent with the origin of the hybrid from a mating between C. neomexicanus (NEO) and C. t. punctilinealis (PUN). Other abbreviations are: UNI, C. uniparens; MAR, C. t. marmoratus. Arrow indicates sites of sample application; anode is to the right.
