Comparative study of red‐cell enzyme polymorphism in the pika and the rabbit

Abstract
Summary: The variants of seven red‐cell enzyme systems of two families of Lagomorphae (rabbit and pika) are studied by enzymoelectrophoretic determination of isoenzyme distribution.Polymorphism appears in five different enzymes (PGM, AK, G6PD, 6PGD and NADH diaphorase) in the pika and in one system (NADH diaphorase) in the rabbit. The electropherograms of acid phosphatase and LDH do not show any variability in either pikas or rabbits. In the pika, red‐cell enzyme polymorphism is as intense as it is in man.
