The full OR repertoire of 58 mammalian genomes. The sequenced genomes of 58 ecologically and phylogenetically diverse mammals were mined for OR gene sequences. The number of functional ORs (yellow bars) and non-functional ORs (grey bars) in the full OR gene repertoire varies between different species. Species are ranked based on the size of their functional repertoire. The coverage of the genomes from which these data were mined, as noted in their assembly builds online, are also included with “C” representing “complete” for human and mouse.
