Fig. 13. Electrophoretic phenotypes of PEPA, a dimeric enzyme, for 12 lizards; letters and labeling as in figure 11, except asterisk marks hybrid (AMNH R145146) that received the callele from MAR instead of the ballele (coincidentally, this is the only hybrid karyotyped that has a fissioned Xchromosome). The callele occurs in other individuals of MAR, the dallele in others of both MAR and SEP. Anode is to the right.
