KARYOTYPES OF 5 SUB-ANTARCTIC BIVALVE SPECIES
International audience Chromosomes of five subantarctic species were studied from mitotic metaphases using cell suspension techniques. Among the Protobranchia, Malletia gigantea has a diploid chromosome number of 2n = 38 with five metacentric, seven submetacentric, five subtelocentric and one teloce...

International audience Chromosomes of five subantarctic species were studied from mitotic metaphases using cell suspension techniques. Among the Protobranchia, Malletia gigantea has a diploid chromosome number of 2n = 38 with five metacentric, seven submetacentric, five subtelocentric and one telocentric pairs, and Yoldia (Aequiyoldia) woodwardi also shows 2n = 38 but with ten metacentric, six submetacentric and three subtelocentric pairs. Among the Lamellibranchia, the pterioidan Limatula pygmaea has 2 n = 38 with six metacentric, eleven submetacentric and two subtelocentric pairs, the veneroidan Cyclocardia astartoides has 2n = 30 with five metacentric and ten telocentric pairs and the anomalodesmatan Laternula elliptica has 2n = 40 with two metacentric, one submetacentric, two subtelocentric and fifteen telocentric pairs. Our results indicate that in all the Nuculoidea studied so far, a diploid number of 2n = 38 has been found. In addition, the karyotypes show a close overall appearance in relative lengths with a majority of metacentric-submetacentric chromosomes. The species differ in the proportion of the different morphological types of chromosomes. In the Lamellibranchia, each species corresponds to a particular case within their respective orders (Pterioida, Veneroida, Anomalodesmata). |
