      Most teleost species, especially freshwater groups such as the Esocidae which are the closest relatives of salmonids, have a karyotype comprising 25 pairs of acrocentric chromosomes and 48–52 chromosome arms. After the common ancestor of salmonids underwent a whole genome duplication, its karyotype would have chromosome arms, and this is reflected in the modal range Cited by: List of works cited (P-Z) Site Search.

    Genetics and Fish Breeding provides a thorough review of this important subject, highlighting species which are bred commercially, such as salmon, trout, carp and goldfish. The author, who is an acknowledged expert in this subject, has drawn together a wealth of information, providing a book which should be bought by all fish biologists, fisheries scientists, geneticists and aquarists. Abstract. Despite large karyotype differences between parental species, the hybrid progeny of the sea trout (Salmo trutta) females (2n = 80, FN = ) and the Atlantic salmon (Salmo salar) males (2n = 58, FN = 74) may be viable and even hybrids would pose threat to natural populations of parental species through backcrossing, gonadal development in the sea trout × Atlantic salmon.

Salmonidae is a family of ray-finned fish, the only living family currently placed in the order includes salmon, trout, chars, freshwater whitefishes, and graylings, which collectively are known as the Atlantic salmon and trout of the genus Salmo give the family and order their names.

Salmonids have a relatively primitive appearance among the teleost fish, with Class: Actinopterygii. Abstract. The chromosomes of the Atlantic salmon, Salmo salar (2n=58) are, on average, larger than those of the trout, S.

Manipulation of chromosomes or chromosome sets is not used in animal breeding although it is a powerful tool in plant genetics. There seems no reason why such techniques should not be applied to fish breeding where, in contrast to the situation in most animals, the breeder can handle the gametes separately and has some control of the developing zygote after by:   Chromosomal rearrangements between European and North American Atlantic salmon.

The linkage maps constructed for European and North American Atlantic salmon have 3, SNPs in common, which allowed us to perform a comprehensive comparison of chromosomal structures between Atlantic salmon from either side of the Atlantic by: unique chromosome arm fusions and fissions.

In this study, we identify orthologous chromosome arms within the salmonids using available RADseq salmonid linkage maps along with a new high-density linkage map ( markers) constructed for the Salvelinus genera (Brook Charr S. fontinalis).Cited by: 4.

Consistent with the relationship, we would like to make you aware of some. Polyploidy is the state of a cell or organism having more than two paired sets of species whose cells have nuclei are diploid, meaning they have two sets of chromosomes—one set inherited from each r, some organisms are polyploid, and polyploidy is especially common in addition, polyploidy occurs in some tissues of animals that are otherwise diploid.

Chromosome preparation involved exposing a growing culture to colchicine. The cells were harvested, flattened, expanded, fixed, and stained. Chromosomes were characterized by selecting metaphase cells from stained preparations of each cell culture, and determining the number of chromosomes per cell and each chromosome's : Bruce B.
