摘要：
Genetic differentiation and evolutionary relationships among 12 populations, representing three subspecies of the polytypic Idotea chelipes were studied by examining geographic variation at 13 loci assayed using polyacrylamide gel electrophoresis. Interbreeding tests and isozyme variations were investigated to compare these three subspecies and Idotea balthica and to see whether morphological differences coincided with genetic differentiation. A dendrogram using Nei's genetic distance values and a pattern of speciation are reported. The taxinomic status, both specific and subspecific, were confirmed. (C) Inra/Elsevier, Paris.
