[Quantitative analysis of adult morphology in eudiploids and three types of trisomics of Pleurodeles waltlii (Amphibia, Urodela) (author's transl)].

The results of a comparative quantitive study of morphology in eudiploids and three types of trisomics of adult Pleurodeles waltlii are discussed. General morphologies are specified by mean measurement values. Statistical bivariate analysis demonstrate differential growths and give some new details on sexual dimorphism. Trisomies 8 and 11 have opposite effects on growth allometries, while no significant effect of trisomy 10 has been detected. As a rule, characters of trisomics are more variable than those of diploids.
