    Abstract:
    We present three idiograms of equine chromosomes, R-banded after BrdU incorporation and stained by the fluorochrome-photolysis-Giemsa technique. The haploid set of prometaphasic chromosomes shows 591 bands (range 7-38 per chromosome), the early metaphasic set 404 (range 5-26), and the midmetaphasic set 272 (range 3-18). Following cell synchronization with thymidine, more than twice as many R-bands were revealed on the resulting prometaphasic chromosomes, making possible the establishment of a very accurate and characteristic representation of this banding pattern in the domestic horse.
