| Abstract: | - 1.1. Myoglobins from heart and skeletal muscle of turtles were analyzed by thin-layer isoelectric focusing.
- 2.2. Within the subfamily Emydinae, variation in the occurrence of two myoglobin electromorphs (pI 6.8 and 6.9) was detected.
- 3.3. Patterns of myoglobin polymorphism support dividing the Emydinae into two subfamilies and help resolve controversial theories on relationships of the genus Deirochelys.
- 4.4. Possible adaptive significance of the myoglobin variants (isoforms) remains to be determined.
