Appearance of a genetically-based pollution resistance in a marine gastropod, Nucella lapillus, in southwest Brittany: a new case of Dumpton Syndrome
International audience Most neogastropod species exhibit masculinization of the female when subject to tributyltin (TBT) pollution (a process known as 'imposex'). To date, the dog-whelk Nucella lapillus is seemingly unique in having a genetic deficiency (termed Dumpton syndrome or DS) that...

To date, the dog-whelk Nucella lapillus is seemingly unique in having a genetic deficiency (termed Dumpton syndrome or DS) that disrupts the development of normal male sex organs, its presence being readily recognizable by the underdevelopment, or non-development (aphally), of the penis, and incomplete formation (non-closure) of the vas deferens, causing a split prostate.

International audience Most neogastropod species exhibit masculinization of the female when subject to tributyltin (TBT) pollution (a process known as 'imposex').
