Fig. 4From: Variations in 5S rDNAs in diploid and tetraploid offspring of red crucian carp × common carpMultiple 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 gapsBack to article page
