Resolving the Taxonomic Status of Chamelea gallina and C. striatula (Veneridae, Bivalvia): A Combined Molecular Cytogenetic and Phylogenetic Approach

Figure 2

FISH mapping of 5S rRNA (5S, red), 28S rRNA (28S, magenta), and H3 histone gene (H3, green) probes to mitotic metaphase chromosomes of striped venus clams Chamelea striatula from Pontevedra (CST Pon) and Chamelea gallina from Cádiz (CGA Cad), Valencia (CGA Val), and Italy (CGA Ita) counterstained with DAPI. The corresponding karyotypes and schematic representations of the signal bearing chromosomes are also included. Note that all chromosome pairs present a single signal with the exception of CST Pon chromosome pair 5 that bears both 5S rDNA and H3 histone gene clusters. Scale bars, 5 μm.
