TL;DR: Genomic sequence analysis of an OSU-142 bacterial artificial chromosome clone positive for all three IgH isotypes revealed that IgT utilizes the standard rainbow trout V(H) families, but surprisingly, the IgT isotype possesses its own exclusive set of D and J elements for the generation of diversity.

TL;DR: This work has shown that it is possible to suppress the first mitotic division offish eggs with high-pressure or -temperature treatments applied at the time of first cleavage to produce mitotic gynogenetic diploids and tetraploids.

TL;DR: Placement of the sex-determining region appears telomeric in brown trout, Atlantic salmon, and Arctic charr, whereas an intercalary location for SEX may exist in rainbow trout, and three hypotheses are proposed to account for the relocation.

TL;DR: Putative homeologous relationships among linkage groups, resulting from the autotetraploid nature of the salmonid genome, have been revealed based on the placement of duplicated microsatellites and type I loci.

TL;DR: Two modes of chromosome evolution are found in the salmonids: in the Coregoninae and the Salmoninae the chromosomes have evolved by centric fusions of the Robertsonian type decreasing chromosome numbers (2n) while retaining chromosome arm numbers (NF) close to that finding in the hypothetical tetraploid ancestor so that most extant taxa have either type A or type B karyotypes.
