Before revision:  which provide new expectations for the distributions of genotypic and genetic polymorphism under increasing clonal rates . Contrasting shoot life span and rhizome turnover lead to the prediction of a decreasing influence of asexual reproduction  along a gradient from Posidonia oceanica to Cymodocea nodosa, Zostera marinaand Zostera noltii , which should be reflected by decreasing departure from Hardy-Weinberg equilibrium (Fis) and increasing genotypic diversity (R).
