Over de genetische afstamming van Rapana venosa (Gastropoda: Muricidae) uit de Noordzee

The invasive mollusc Rapana venosa has European populations in the North Sea, Quiberon Bay (Brittany, France), Adriatic Sea and Black Sea. Specimens from these locations were sequenced by E. Chandler from the Virginia Institute of Marine Science (VIMS) for their genetic lineage. Apparently the mitochondrial genes COI and ND2 show that all samples have the same mitochondrial genetic sequence. This means that there is no genetic variation within the maternal lineage of the European populations of Rapana venosa. The populations in Europe probably originated from one single female or egg case, which could explain the presence of a single maternal haplotype.
