Background Autotetraploid Carassius auratus (4nRCC, 4n = 200, RRRR) was derived from the whole genome duplication of diploid red crucian carp (Carassius auratus red var.) (2nRCC, 2n = 100, RR).

Formation of the synaptonemal complex in a gynogenetic allodiploid hybrid fish
Introduction: The correct pairing and separation of homologous chromosomes during meiosis is crucial to ensure both genetic stability and genetic diversity within species. In allodiploid organisms, synapsis often fails, leading to sterility.

Effective monitoring of freshwater fish [PDF]
AbstractFreshwater ecosystems constitute only a small fraction of the planet's water resources, yet support much of its diversity, with freshwater fish accounting for more species than birds, mammals, amphibians or reptiles. Fresh waters are, however, particularly vulnerable to anthropogenic impacts, including habitat loss, climate and land use change,

Carcinogens and Cancers in Freshwater Fishes [PDF]
Epizootics of neoplasms in freshwater fish species are considered in relation to circumstantial and experimental evidence that suggest that some epizootics of neoplasia of hepatocellular, cholangiocellular, epidermal, and oral epithelial origin may be causally related to contaminant exposure.

Background Interspecific postzygotic reproduction isolation results from large genetic divergence between the subgenomes of established hybrids. Polyploidization immediately after hybridization may reset patterns of homologous chromosome pairing and ...

Genetic interactions between nuclear and mitochondrial genomes always play an important role in growth and development. However, it is not feasible to directly perform these studies in some animals. The reciprocal hybrid fishes obtained from intergeneric
