- 論文の詳細を見る
Two shell color types of the exotic bivalve Corbicula fluminea were collected in Kyoto city, Japan. DNA microfluorometry revealed that both types were diploids with non-reductional spermatozoa. Maternal chromosomes were found to be extruded as two polar bodies at the first meiosis, and the second meiosis could not be observed. Only the male pronucleus was present in the egg cytoplasm and became metaphase chromosomes at the first mitosis. The present study indicates that the diploid C. fluminea in Japan has the same mode of androgenetic reproduction as the triploid C. leana.
