| Abstract: | Replication banding technique was applied to the chromosomes of Salmo salar, Salmo trutta, and Oncorhynchus mykiss. The in vitro technique has proved more advantageous than the in vivo technique due to a higher number of bands obtained. The comparison of these replication banding patterns has revealed that some chromosomes of Salmo trutta karyotype appeared associated with Salmo salar and Oncorhynchus mykiss karyotypes by single chromosomal rearrangements. |
