Notes:
Summary Evidence has previously been presented on the occurrence spontaneous variations in the electrophoretic mobility (EM) of glucose-6-phosphate dehydrogenase (G6PD E.C. 1.1.1.49) in laboratory clones of parthenogenetically reproducing Daphnia (Ruvinsky et al. 1983). The present study is concerned with a natural population of Daphnia living under the extreme conditions of shallow, dessicating pond. The number of individuals having the slow (S) variant of the EM of G6PD increased sharply during their 1.5 month life span. This increase is suggested to result from alternational variability related to activation of latent genetic material.
