Fig. 4.

Multiple alignment of the 82-bp NTS units of 5S rDNAs in parental progenitors and hybrid progenies. Two representative 82-bp NTS units of both parental fishes and four representative 82-bp NTS units of both diploid hybrid 2nF₁ and allotetraploid fish 4nF₂₂ are shown. The nucleotide sites in red and green background are red crucian carp-specific locus and common carp-specific loci, respectively. The nucleotide sites in gray background are loci that vary in the hybrid progeny. The dashes represent gaps
