Ostracodes are important indicator species, the evolution of which has been studied in both paleontological and recent contexts. Their small sizes has effectively prevented the application of electrophoresis on them. We report here an array of techni

Eight parental plants of tansy, Chrysanthemum vulgare, belonging to the camphor or thujone chemotypes, were crossed in 31 hybridizations. The progeny, containing 513 plant individuals, were analyzed by gas chromatography, which reveals at least three

The genic variability at twenty loci in marginal, submarginal and central populations of Drosophila subobscura has been studied by starch gel electrophoresis. The samples from marginal populations orginate from Finland, the submarginal ones from Swed

The patterns of genetic polymorphism, detected by routine enzyme electrophoresis, have been followed in natural populations of two parthenogenetic species of Solenobia: S. lichenella and S. fennicella. S. lichenella is assumed to be a parthenogenetic

Otiorhynchus scaber is a common weevil throughout northern Europe. It is tetraploid and parthenogenetic in this area. A total of 75 electrophoretically definable clones have been identified in northern Europe and they all appear to represent a monoph
