The increasing use of molecular tools to study populations of
clonal organisms leads us to question whether the low
polymorphism found in many studies reflects limited genetic
diversity in populations or the limitations of the markers
used. Here we used microsatellite datasets for two sea grass
species to provide a combinatory statistic, combined with a
likelihood approach to estimate the probability of identical
multilocus genotypes (MLGs) to be shared by distinct
individuals, in order to ascertain the efficiency of the markers
used and to optimize cost-efficiently the choice of markers
