Distant hybridization leads to different ploidy fishes
2010
Abstract: ...study shows that distant hybridization or the combination of this method with gynogenesis or androgenesis lead to
different ploidy fishes with genetic variation, including fertile tetraploid hybrids, sterile triploid hybrids, fertile diploid hybrids,
fertile diploid gynogenetic fish, and their derived progenies. The formations of the different ploidy fishes depend on the genetic
relationship between the parents. In this study, several types of distant hybridization, including red crucian carp (Carassius auratus
red var.) (2n=100, abbreviated as RCC) (a (TM) Euro)xcommon carp (Cyprinus carpio L.) (2n=100, abbreviated as CC) (a (TM),), and
RCC (2n=100) (a (TM) Euro)xblunt snout bream ( Megalobrama amblycephala) (2n=48, abbreviated as BSB) (a (TM),) are described.
In the distant hybridization of RCC (a (TM) Euro)xCC (a (TM),), bisexual fertile F... ...and males of 4nAT developed into diploid
gynogenetic hybrids and diploid androgenetic hybrids, respectively, by gynogenesis and androgenesis, without treatment for
doubling the chromosome. Improved tetraploid hybrids and improved diploid fishes with genetic variation were derived from the
gynogenetic hybrid line. The improved diploid fishes included the high-body RCC and high-body goldfish. The formation of the
tetraploid hybrids was related to the occurrence of unreduced gametes generated from the diploid hybrids, which involved in
premeiotic endoreduplication, endomitosis, or fusion of germ cells. The sterile triploid hybrids (3n=150) were produced on a large
scale by crossing the males of tetraploid hybrids with females of diploid fish (2n=100). In another distant hybridization of RCC (a
(TM) Euro)xBSB (a (TM),), different
