Fig. 18. Electrophoretic phenotypes of five proteins as expressed on separate gels. PEPA, a dimeric enzyme, for three lizards. LDH1, a tetrameric enzyme, for three lizards. ESTD, a dimeric enzyme, for three lizards. sMDH, a dimeric enzyme, for four lizards. TF, a monomeric enzyme, for six lizards; white dots mark the three isozymes from the hybrid. Letters below gel identify allozymes based on alleles present (table 13). Lanes for individual lizards are labeled beside the gel (with genotype) as follows: I, A. inornata; M, A. tigris marmorata; N, A. neomexicana; NC, A. neomexicana from Conchas Lake; NF, A. neomexicana from Fort Sumner; N 3 S, the hybrid; S, A. sexlineata viridis. Anode is to the right, ^ indicates relative position of sample applications.
