Poecilia formosa and other
gynogenetic animals are dependent for reproduction on related free-living sperm-donor species and are thus unable to extend their geographical ranges or potential evolutionary survival beyond those of their sympatric hosts [19].
In this study, ruptured chromosome fragments were identified as a result of the karyotype analysis in haploid
gynogenetic embryos.
Gamete Collection and Induction of the
Gynogenetic Development.
Growth and feed utilization in two strains of gibel carp, Carassius auratus gibelio: paternal effects in a
gynogenetic fish.
1976.--Morphology of androgenetic and
gynogenetic grass carp, Ctenopharyngodon idella (Valenciennes).
For example, because
gynogenetic fish inherit genes only from their mothers, they normally are all females.
As previously reported (Elder and Schlosser 1995), all 464 individual gynogens fingerprinted from the Lost Ponds drainage were genetically identical, indicating that a single
gynogenetic clone occupied the entire drainage.
In
gynogenetic development, spermatozoa stimulate the development of eggs but do not contribute paternal genome to the offspring.
But the
gynogenetic fertilization process also decreases genetic variability within those offspring that do survive, enabling us to more easily select and enhance a particular trait.
(2000) compared nuclear behavior between normal and
gynogenetic eggs of Crassostrea gigas using DAPI staining and epifluorescence microscopy.
Interactions between a bisexual fish species and its
gynogenetic sexual parasite.
In this study, black spot parasites of the Phoxinus eos-neogaeus
gynogenetic cyprinid complex, in Voyageurs National Park, were used to re-test the Red Queen Hypothesis, which suggest that sexual fish have an advantage over clonal fish regarding parasite loads.
