The unusual allotetraploid form with unequal contribution of chromosome sets was
discovered from the gynogenetic offspring of Carassius auratus gibelio stimulated by red …

Background The establishment of the bisexual fertile fish hybrid lineage including the
allodiploid and allotetraploid hybrids, from interspecific hybridization of red crucian carp …

The ploidy of silver crucian carp Carassius auratus gibelio individuals, originating from nine
natural habitats of Hungary, was estimated by erythrocyte nucleus area analysis. On the …

In gynogenesis, sperm from related species activates egg and embryonic development, but
normally does not contribute genetically to the offspring. In gibel carp, Carassius auratus …

The establishment of the tetraploid organism is difficult but useful in genetics and breeding.
In the present study, we have artificially established an autotetraploid fish line (F2–F8) …

Distant hybridization leads to obvious changes in genotypes and phenotypes, giving rise to
species with novel capabilities and adaptabilities. The establishment of autotetraploid …

The speciose neotropical genus Characidium has proven to be a good model for
cytogenetic exploration. Representatives of this genus often have a conserved diploid …

A single female with 206 chromosomes and another 26 females with 156 chromosomes
identified as Prussian carp, Carassius gibelio, and 5 individuals with 100 chromosomes …

Chromosome set manipulation such as polyploidy and gynogenesis have been widely
applied for genetic improvement of freshwater domesticated species. However, few …

Background Allopolyploids generally undergo bivalent pairing at meiosis because only
homologous chromosomes pair up. On the other hand, several studies have documented …
