Fig. 33 in Hybridization Among Western Whiptail Lizards (Cnemidophorus Tigris) In Southwestern New Mexico: Population Genetics, Morphology, And Ecology In Three Contact Zones
Fig. 33. Gels illustrating uncommon electrophoretic variants in specimens of C. tigris. Top. Uncommon polymorphisms observed at sMDH and mMDH. Bottom. Uncommon polymorphisms observed at sAAT and mAAT. All four enzymes are dimeric, as indicated by the threebanded patterns characteristic of heterozygous individuals. The ab genotype at the sMDH locus was observed in only one specimen of C. t. aethiops; the bc genotype at the mMDH locus was observed in only one specimen of C. t. marmoratus from Dona Ana County, New Mexico, distant from the contact region. The a+b genotype of sAAT was observed in only one specimen of punctilinealis from site 49, distant from the contact region. Arrows indicate sites of sample application; anode is to the right.
Fig. 25 in Hybridization Among Western Whiptail Lizards (Cnemidophorus Tigris) In Southwestern New Mexico: Population Genetics, Morphology, And Ecology In Three Contact Zones
Fig. 25. Identification of esterase loci illustrating the diversity of diagnostic locus EST2 in muscle homogenates. Top. Gel stained with 4methylumbelliferyl butyrate, a substrate that enhances the activity of EST1 and minimizes that of EST2. Bottom. Opposite half of the same gel stained with 4 methylumbelliferyl acetate, a substrate that enhances the activity of EST2. The aallele of EST2 is diagnostic for marmoratus; the ballele is diagnostic for punctilinealis. Note that alleles for EST1 are mislabeled, owing to discovery of the rare aallele (table 22) after labeling of this figure. Therefore, in this figure read the aallele of EST1 as b, and read the ballele as c, to be consistent with table 6. These fluorescent banding patterns were photographed in ultraviolet light; arrows indicate sites of sample application; anode is to the right.

Fig. 29 in Hybridization Among Western Whiptail Lizards (Cnemidophorus Tigris) In Southwestern New Mexico: Population Genetics, Morphology, And Ecology In Three Contact Zones
Fig. 29. Banding patterns illustrating the high polymorphism in PEPD and GPI. Left. Gel stained for PEPD, the most polymorphic of the loci examined. The gel shows six combinations of the five PEPD alleles. The a and balleles had the highest frequencies in punctilinealis; the callele was highest in marmoratus. Right. Gel stained for GPI. The a and balleles had their highest frequencies in marmoratus; the callele was most frequent in punctilinealis. As this analysis utilized hemolysates, hemoglobin appears as a cathodally migrating band. Arrows indicate sites of sample application; anode is to the right.
