impaternata and report evidence that impaternata arguably has eccentric reproductive biology due to the conjunction of gynogenesis
and haplodiploid sex determination in its life cycle.
The first gynogenesis
study was conducted on trout (Onchorhynchus mykiss) by Opperman .
Moreover, eggs coming from the gynogenetic DH females may be used for another round of gynogenesis
to produce clonal fish .
Application of the scale cover gene (N) to identification of type of gynogenesis
and determination of ploidy in common carp.
These homozygous doubled haploids have been induced via either androgenesis (pollen or anther culture) or gynogenesis
(ovule or ovary culture) processes, or induced by pollination with irradiated pollen (Islam, 2010; Chen et al., 2011; Lazaridou et al., 2011; Galazka and Niemirowicz-Szczytt, 2013).
Several efforts have been made to produce successive all-male populations by combining induction of sex reversal and gynogenesis
(Liu et al., 2007, 2013) as well as application of sex-linked markers (Wang et al., 2009; Dan et al., 2013).
Chromosome doubling was achieved by several means; by applying colchicine and/or oryzalin, both to germinating seeds and to areoles (Te-Zur et al 2011b), by crossing between genotypes of various ploidy where some offspring were found to be of different ploidy than the parents (Tel-Zur et al 2004), or alternatively--by gynogenesis
(Benega-Garcia et al 2009b).
