[i] The columns Genes (average) and CDS (average) provide values averaged over all the sequences (178 in h178 and 42 in Gen178). Gene density provides the percentage of nucleotides that occur in genic regions (exons, introns, and UTRs), and the number of kilobases per gene. CDS no. exons is the average number of coding exons per sequence, and CDS density is the percentage of nucleotides that occur in coding regions.
