Abstract
The karyotypes of two species in the name of Triturus vulgaris and Triturus karelinii, belonging Salamandridae family of Urodela order were analyzed. Chromosome numbers of both the Triturus species were identified as 2n=24 and chromosomes forming karyotypes clustred in three group, long, medium and short by their lengths. I, VIII and XIIth chromosome pairs in Triturus vulgaris showed metacentric morphology whereas the same chromosomes showed submetasentric morphology in Triturus karelinii. VI, VII, IX, X and XIth chromosome pairs in Triturus vulgaris were found to be submetasentric compared to metasentric morphology of same chromosome pairs in Triturus karelinii. The other chromosome pairs II, III, IV and V-th were found to have metasentric morphology in both species. According to our measurements, chromosomes of Triturus karelinii were found to be long and to have more regular line and intrakaryotypic variations between chromosomes were determined as low.
