AbstractIsozyme characters, exclusive of allozymes (alleles), are potentially useful in phylogenetic investigations. Such data have been derived from the multilocus L-lactate dehydrogenase (LDH) enzyme system. Among non-avian reptiles, the classes of potential characters include (1) and number of loci encoding LDH, (2) heterotramer patterns, (3) tissue-specific patterns of gene expression, (4) tissue-specific posttranslational modification and (5) reversed relative mobility of the skeletal muscle (Ldh-A) and heart-predominating (Ldh-B) loci. The first three potential characters show variation among the species. However, because of the limited number of alternative states, and evolutionary pathways that variants can follow, it appears that such data will have limited applicability in phylogenetic investigations.
