A great deal of information is known regarding the process of sex differentiation in fish, and
the mechanisms involved in primary sex determination are now beginning to be defined. A …

The rainbow trout (Oncorhynchus mykiss) is one of the most widely studied of model fish
species. Extensive basic biological information has been collected for this species, which …

The large 45S rDNA chromosome sites have often been analyzed in fish. In contrast, little is
known about the 5S genes in this animal group. In the genus Leporinus, the NOR …

A single NOR-bearing chromosome pair was identified by silver nitrate staining in a previous
study of the fish Prochilodus argenteus from the S ã o Francisco River (MG, Brazil), with a …

We compared the Y-chromosome linkage maps for four salmonid species (Arctic charr,
Salvelinus alpinus; Atlantic salmon, Salmo salar; brown trout, Salmo trutta; and rainbow …

In higher eukaryotes, the 5S ribosomal multigene family (5S rDNA) is tandemly organized in
repeat units composed of a coding region (5S rRNA gene) and a nontranscribed spacer …

In this paper we describe Southern blot hybridization results probed with 5S rRNA genes for
several Neotropical fish species representing different taxonomic groups. All the studied …

Karyotype and chromosomal characteristics from 3 allopatric populations of Hoplias
malabaricus, cytogenetically the most studied Erythrinidae taxon, were investigated using …

Cytogenetic studies were carried out in the fish, Hoplias malabaricus, from the Parque
Florestal do Rio Doce (Brazil). This population is characterized by 2n= 42 chromosomes for …

We searched for sex-specific DNA sequences in the male and female genomes of African
catfish, Clarias gariepinus (Burchell, 1822) by comparative random amplified polymorphic …
