Unisexual hybrids between Fundulus diaphanus and Fundulus heteroclitus were found in low proportions at intermediate salinity in Porter's Lake, Nova Scotia. One clone accounted for 72% of the hybrids, with most other hybrids being different at a single microsatellite allele. This clone thrives over a wide range of salinities, suggesting a general-purpose genotype.
