Abstract
We have analyzed the EcoRI restriction pattern of ribosomal genes (rDNA) isolated from several organs of single individuals of the newt Triturus vulgaris by Southern blotting and hybridization with corresponding Xenopus probes (r11 and r12). Using length polymorphism of rDNA spacers as a molecular marker, it became evident that in individual newts the pattern of ribosomal genes is not always constant but varies between different tissues of the same animal suggesting the occurrence of genome alterations during ontogenesis.
