Sex ratios in the progeny of androgenetic and gynogenetic
YY male Nile tilapia, Oreochromis niloticus L.
Survivability of salmonid androgenetic and gynogenetic
early embryos is lower in eggs that were subjected to the HHP shock [30,31].
There are no known gynogenetic
birds or mammals .
fish producing method and the different heat-shock applications mentioned in this study enhanced the survival rate of gynogenetic
Moreover, eggs coming from the gynogenetic
DH females may be used for another round of gynogenesis to produce clonal fish .
gibelio fish have two different reproductive activities including gynogenetic
and bisexual (Bostanci et al., 2007).

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).
