Abstract
The LDH isozymes were surveyed in bacterized cultures of syngens 1, 3, 12, and 13 of Paramecium caudatum by polyacrylamide gel electrophoresis. All the examined stocks of different syngens except one stock in syngen 3 had a single common LDH isozyme, and intra- and intersyngenic variation was not observed except for the one stock in syngen 3. Breeding data using the exceptional stock indicated that the LDH isozymes of P. caudatum are controlled by two codominant alleles at a single locus whose products aggregate randomly, forming a dimer.
