(Received 2 February 2005; accepted 26 August 2005)
In the genus Fucus, the character dioecy/hermaphroditism has undergone multiple state changes and hybridization is possible
between taxa with contrasting mating systems, e.g. between the dioecious Fucus vesiculosus and the hermaphrodite F. spiralis.
In the context of mating system evolution, we evaluated the potential consequences of hybridization by studying the variation
