Evolutionary Dynamics of rDNA Clusters in Chromosomes of Five Clam Species Belonging to the Family Veneridae (Mollusca, Bivalvia)

Figure 4

Schematic representation of the distribution of major (red) and 5S (green) rDNA clusters on chromosomes of Veneridae. Yellow marks indicate linkage of major and minor rDNAs. The species are organized according to the phylogenetic tree (clade A) proposed by Chen et al. [6] (left) and also assigned to subfamilies according to the accepted traditional classification (right).
