Abstract

Cloned satellite DNAs that hybridize primarily to C-band-positive regions of felid and canid chromosomes were used to probe the organization of satellite families in the genomes of 16 species of felids and 15 species of canids. Southern-blot and quantitative dot-blot experiments demonstrated that satellite families within the great cats (panthera lineage) vary considerably in regard to amount and/or sequence mismatch and vary some-what in regard to restriction patterns. Satellite families within the canids appeared to be more uniform in regard to both amount/sequence and restriction patterns, although some canid species did differ significantly from the consensus in both respects. Even though intrafamilial satellite restriction patterns were generally similar, every species could be shown to have a unique, characteristic pattern.
