Résumé

Une technique est décrite permettant d'obtenir des images chromosomiques particulièrement favorables fournies par des blastulas d'Axolotl. A partir de ce matériel le caryotype de cette espèce est analysé.

Cette étude introduit des problèmes concernant la signification de l'hétérochromatine, ainsi que les rapports entre satellite et nucléoles.

Summary

A technique is described by which especially clear pictures of the chromosomes in blastulae of Ambystoma mexicanum can be obtained. An analysis of the karyotype is given. This study touches upon problems concerning the significance of heterochromatin and the relation between satellites and nucleoli.
