REPORT ON THE PROGRESS OF STANDARDIZATION OF THE G-BANDED CANINE (CANIS-FAMILIARIS) KARYOTYPE

Karyotyping of dog chromosomes is a difficult task owing to the high d iploid number of chromosomes (2n=78) and the similar morphology of aut osomes, all of which are acrocentrics. In this report 22 of the 39 G-b anded chromosome pairs and their corresponding ideograms have been sta ndardized. The ideogram comprises altogether 235 bands. The need for t he introduction of molecular techniques such as chromosome painting an d physical mapping of genetic markers for the identification of small acrocentrics is discussed.
