  1. (a)From a larger set of OR sequences retrieved from ENSEMBL and GENBANK, we characterized a subset of true OR genes by multiple alignment of AA sequences, phylogenic tree construction and BLAST analysis. DNA samples used by the BROAD institute to determine the genomic sequences were for each species extracted from a single fish with 2 N chromosomes.
