Characterization of heterochromatic regions in two Triturus alpestris subspecies (Urodela: Salamandridae).
The fluorescence analysis carried out in Triturus alpestris alpestris and Triturus alpestris cyreni subspecies has revealed differences related to the content and distribution of AT-rich, GC-rich and non-fluorescent heterochromatic bands. These results provide new evidence on the chromosome differentiation undergone in their phylogenetic splitting.
