A YY-male Oreochromis niloticus strain developed from an exceptional mitotic gynogenetic

Diversity and distribution of gynogenetic
hybrids between Fundulus diaphanus and Fundulus heteroclitus in Porters Lake (Nova Scotia) in relation to salinity.
Induced development of triploids and diploid gynogenetic
and androgenetic fish includes 1 to 10 min exposure of activated eggs to HHP of 48.3 to 79.3 MPa in order to damage spindle microtubules and to disrupt extrusion of the 2nd polar body or to inhibit 1st cell cleavage [6, 7].
impaternata is a unisexual clonal species of hybrid origin, arguably with a gynogenetic
mode of reproduction in which (i) the parthenogenetic production of diploid female eggs by its queens is spermdependent, requiring allospecific copulation followed by interaction without fertilisation between their unreduced oocytes and nonconspecific sperm cells and (ii) sperm necessary for this purpose is likely acquired by the gynes through copulation with technically allospecific males produced from eggs laid by impaternata queens and reared in impaternata nests.
For other molluscs, different models for sex determination involving putative sex chromosomes have been proposed and have been inferred after observing the sex ratios in gynogenetic
progeny and triploids (Allen et al.
In haploid gynogenetic
embryos, the ruptured chromosome fragments were identified at Figure 2C.
However, the gynogenetic
development may be induced intentionally.
gibelio is gonochoristic and has gynogenetic
reproductive properties, because of which C.
Several factors have been reported to affect the gynogenetic
potential of ovules/ovaries in cucumber, including genotypes of donor plants, low/high temperature pretreatment, female gametophyte developmental stages, growth regulators or other components of media, and culture conditions (GACopyrightmes-Juhasz et al., 2002; Suprunova and Shmykova, 2008; Diao et al., 2009; Chen et al., 2011; Galazka and Niemirowicz-Szczytt, 2013; Mishra and Goswami, 2014).
