Most presently known unisexual fish employ one of two modes of sperm-dependent reproduction: gynogenetic systems, where the entire genomic constitution of the mother is inherited intact and sperm is required only to initiate cleavage (Dawley 1989); and hybrid-ogenetic systems, where only the ancestral maternal lineage is clonal and the paternal complement is replaced each generation by sperm from a related sexual species (Schultz 1969, 1977, Vrijenhoek 1984a, b).
