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 .
In this study, ruptured chromosome fragments were identified as a result of the karyotype analysis in haploid gynogenetic
Gamete Collection and Induction of the Gynogenetic
Growth and feed utilization in two strains of gibel carp, Carassius auratus gibelio: paternal effects in a gynogenetic
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.
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
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.
