Abstract Three X chromosome-specific bovine cosmids were used for fluorescencein situ hybridization mapping on reindeer (Rangifer tarandus) chromosomes, to test whether such large genomic clones could be used for comparative mapping across distantly related species. All three cosmids showed distinct unique hybridization sites on the reindeer X. Comparative map locations of these cosmids, together with the relative C-banding and genome size data on the X chromosomes of the two species, provide preliminary indications that the short and long arms of bovine X correspond, respectively, to the long and short arms of the reindeer X. The study also demonstrates that cosmid clones can be used successfully for comparative mapping across species that diverged 35 million years ago.
