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.
