Based on these observations, we broadened the investigation of satellite III distribution to include the other great apes. Remarkably no traces were detected on gorilla, chimpanzee, and human IIq homologs. Conversely, chromosome IIp was positive for the satellite III carrying probe in all examined species (table 1 and see supplementary fig. S3, Supplementary Material online).
