Fig. 49 in Hybridization Among Western Whiptail Lizards (Cnemidophorus Tigris) In Southwestern New Mexico: Population Genetics, Morphology, And Ecology In Three Contact Zones
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.

Fig. 28 in Hybridization Among Western Whiptail Lizards (Cnemidophorus Tigris) In Southwestern New Mexico: Population Genetics, Morphology, And Ecology In Three Contact Zones
Fig. 28. Banding patterns of diagnostic loci sMDHP and PEPB. Top. Gel stained for sMDHP and then counterstained with substrate for PEPB. The sMDHP aallele is diagnostic for marmoratus, the ballele for punctilinealis. Notice how close the a and b bands are to each other. As sMDHP is a tetrameric protein, the fivebanded patterns of heterozygous individuals are often difficult to score with confidence Bottom. Gel stained for PEPB. The ballele is diagnostic for punctilinealis; the c and dalleles are diagnostic for marmoratus. The substrate for PEPB, leucyl.glycyl.glycine, is also a substrate for PEPE which is invariant in C. tigris. Arrows indicate sites of sample application; anode is to the right.
Fig. 27 in Hybridization Among Western Whiptail Lizards (Cnemidophorus Tigris) In Southwestern New Mexico: Population Genetics, Morphology, And Ecology In Three Contact Zones
Fig. 27. Banding patterns of iditol dehydrogenase (IDDH) and diagnostic locus transferrin (TF) Left. Gel stained for IDDH. The ballele occurs in both subspecies; the IDDH aallele is diagnostic for marmoratus, in which it occurs exclusively (excepting hybrids), but at a maximum frequency of about 0.65. Right. Autoradiograph illustrating the localization of TF by binding of radioactive 59Fe. The TF aallele is diagnostic for marmoratus, the ballele for punctilinealis. Arrows indicate sites of sample application; anode is to the right.

Fig. 24 in Hybridization Among Western Whiptail Lizards (Cnemidophorus Tigris) In Southwestern New Mexico: Population Genetics, Morphology, And Ecology In Three Contact Zones
Fig. 24. Dotblot illustrating determination of the 12S ribosomal mtDNA haplotypes of individual lizards from 20 collecting sites across the contact region. The blot was first hybridized with the ASOMAR probe specific for the marmoratus haplotype (Top). After stripping, the blot was hybridized with the ASOPUN probe specific for the punctilinealis haplotype (Bottom). Spillage caused the absence of reactions at positions E10 and G2. DNA of C. inornatus gave the weak positive reaction at position G12 (Top), as discussed by Dessauer et al. (1996b).
Fig. 23 in Hybridization Among Western Whiptail Lizards (Cnemidophorus Tigris) In Southwestern New Mexico: Population Genetics, Morphology, And Ecology In Three Contact Zones
Fig. 23. Dotblot illustrating specificity of the allelespecific oligonucleotide probes (ASOs) DNA samples from 24 lizards from 12 different sites were applied in rows A and C of a strip of nitrocellulose paper. After heat denaturation, the blot was hybridized successively with ASOPUN (Tucson) (Top), ASOMar (Middle), and ASO PUN (Bottom). Note that C. t. punctilinealis samples from sites 49 and 56, west of the contact region, hybridized only to ASOPUN (Tucson (positions 1–3 of row A), in contrast to samples of punctilinealis from the contact region, which hybridized only with ASOPUN (positions 5 and 7 of row C). DNA of C. t. marmoratus from all sites paired with ASOMAR (positions 4–12 of row A, and positions 1–4, 6, and 8–12 of row C)
