Fig. 3From: Divergent evolutionary behavior of H3 histone gene and rDNA clusters in venerid clamsSubterminal H3 histone gene clusters in venerid clams. Examples of FISH to surface spread synaptonemal complexes of Ruditapes philippinarum (RPH) and Venerupis corrugata (VCO) clearly denote the subterminal location of the H3 histone gene clusters (H3, green). 5S rDNA clusters (5S, red) are also subterminal in VCO but intercalary in RPH.
