A Comparative Study on Enzyme Polymorphisms in Sympatric Diploid and Polyploid Populations of Lumbricillus Lineatus (O.F.M.) Enchytraeidae Oligochaeta
The Oligochaete worm Lumbvioillus lineatus is a littoral species often abundantly present in wrack beds. Amphimictic diploid and parthenogenetic tri-, tetra and pentaploid populations have been found. Due to peculiarities in the reproductive behaviour of the parthenogenetic polyploids, two different chromosome “races” have been found to occur together in all the localities studied. The aim of the present study is to compare such two closely related forms occurring in the same environment but subjected to different genetical conditions.
