  1. a A sequence is defined as "intact" if it possesses a full-length OR protein coding sequence that is at least 250 amino-acids long and has seven TM domains.
  2. b A sequence is defined as "pseudogene" if it possesses at least 1 premature stop codon and/or frameshift and/or has less than seven TM domains.
  3. c A sequence is classified as a partial gene if it is shorter than 250 amino-acids and contains at least one sequence gap on the flanking genomic region.
  4. d Numbers indicate the sum of intact genes, pseudogenes and partial genes.
  5. e The percentage of intact OR genes is calculated as the ratio of 100*intact genes/(intact genes + pseudogenes). Numbers in brackets indicate the proportion of intact OR genes assuming that all partial genes will turn out to be pseudogenes (first number) or intact OR genes (second number).
