From: Variations in 5S rDNAs in diploid and tetraploid offspring of red crucian carp × common carp
Organization of the 5S rDNA sequences detected in parental progenitors and hybrid offspring. The 82-bp NTS units in the 5S rDNA sequences in red crucian carp and common carp are marked in red and orange, respectively. The 138-bp IPRs are marked in blue. The three processes, hybridization, polyploidization, and breeding, are marked in different background colors. The highly similar regions in the 5S rDNA sequences of different fishes are marked in the same color
