Abstract
A karyological analysis was carried out on two populations ofTriturus montandoni, one from Poland and another from Rumania. For both samples, morphometric characteristics and C-banding pattern of mitotic chromosomes are provided. Only slight differences between specimens from two geographic localities were found.
Data on chiasma frequency and distribution are presented for male meiosis. No sex-related heteromorphism was found and for none of the chromosomal arms was a consistent absence of chiasmata recorded. There was a relatively high proportion of spermatocyte metaphases I with chiasmata on both arms of all chromosomes in all specimens studied. It is concluded that there are no well-defined sex chromosomes in the chromosomal complement of the maleT. montandoni.
The findings are compared with previous studies on chromosome morphology, C-banding pattern, and meiosis in closely related species,T. vulgaris andT. helveticus.
