  author={Susumu Ohno and Jun-ichi Muramoto and Lawrence C. Christian and Niels B. Atkin},
Evidence suggesting that the goldfish and the carp of the family Cyprinidae are tetraploid species in relation to other members of the same family were presented. The two barb species, Barbus tetrazona and Barbus jasciatus, were chosen as representatives of diploid members of the family Cyprinidae. These barbs had the diploid chromosome number of 50 and 52 and the DNA value 20–22% that of placental mammals, while the goldfish (Carassius auratus) and the carp (Cyprinus carpio) had the diploid… 

On the diploid state of the fish order Ostariophysi

According to this study, diploid members of Ostariophysi underwent extensive chromosomal rearrangements as well as steady increases in DNA contents by regional duplication of chromosomal segments.

Duplication of the autosomally inherited 6-phosphogluconate dehydrogenase gene locus in tetraploid species of cyprinid fish

The present study on electrophoretic patterns of 6-phosphogluconate dehydrogenase indicates that such diploid members as Barbus tetrazonamaintain allelic polymorphism at a single gene locus for this enzyme.

Multiple origins of polyploidy in the phylogeny of southern African barbs (Cyprinidae) as inferred from mtDNA markers

Evidence of multiple, independent origins of polyploidy occurring in the African Cyprinine cyprinids provides a significant contribution to the knowledge on the systematic diversity of these fishes, and warrants a thorough taxonomic reorganization of the genus Barbus.

Significant differential gene duplication without ancestral tetraploidy in a genus of mexican fish

The data indicate that even a large proportion of differentially duplicated loci within a group of related fish species is not critical evidence of common tetraploid ancestry, and may be an important component of the genetic differences that separate congeneric conventional diploid species.

Duplicate gene expression in diploid and tetraploid loaches (Cypriniformes, Cobitidae)

Many of the duplicate loci have diverged to unique patterns of expressions in different tissues or different levels of activity within a single tissue, resulting in low levels of duplicate gene expression observed.

Cytogenetic studies of Poecilia (Pisces)

Demonstration of cytogenetic criteria by which females from triploid clones may be clearly distinguished from sympatric diploid specimens of P. formosa or P. mexicana leaves unresolved, for the present, problems of an appropriate systematic designation for natural populations of Triploid gynogenetic fishes.

Recent duplication of the common carp (Cyprinus carpio L.) genome as revealed by analyses of microsatellite loci.

Phylogenetic analysis of several cyprinid species suggests an evolutionary model for this tetraploidization, with a role for polyploidized in speciation and diversification.

Genetic evolution and diversity of common carp Cyprinus carpio L.

Using microsatellites showed that the genome evolution in common carp exhibited two waves of rearrangements: one whole-genome duplication (12–16 million years ago) and a more recent wave of segmental duplications occurring between 2.3 and 6.8 million Years ago.


The present study was undertaken with a hope to obtain any critical information for understanding some evolutional relationship in the Cyprinidae of Japan.

The chromosomes of 11 species of cyprinidae and one cobitidae from Italy, with some remarks on the problem of polyploidy in the cypriniformes

The present paper gives a detailed description of the morphology of the karyotype of 11 Cyprinidae and 1 Cobitidae indigenous to Italian inland waters and the data on the morphology are used in discussing the problem of polyploidization of the chromosomal complement in both the CyprInidae and the whole order Cypr iniformes.



Comparative DNA values and chromosome complements of eight species of fishes

The present study appears to indicate that a series of polyploidization of the original vertebrate genome took place while vertebrates were still aquatic forms. The polyphyletic evolution of

Cytological evidence of constant tetraploidy in the bisexual South American frog Odontophrynus americanus

Odontophrynus americanus has 2n=44 chromosomes in somatic and gonad cells which can be ordered in 11 groups of homologues and there is no indication of abnormalities in ♂ and ♀ gonad development.

The comparative DNA content of 19 species of placental mammals, reptiles, and birds

Comparisons of DNA values obtained from the Feulgen stain content of 19 species of placental mammals, birds and reptiles are by and large in good agreement with previous results obtained from two-dimensional measurements of chromosome area.

Chromosome size and DNA content of species of anemone L. and related genera (Ranunculaceae)

The magnitude of variations in DNA content, the preservation of the karyotype and the tendency towards a simple numerical progression in DNA values, lead us to prefer an interpretation of the evolution of DNA content in terms of differential polynemy to one postulating changes in size of genetic units in an unchanging number of strands per chromosome.
