 The problem that the junk DNA discussion brings up has also been referred to as the ‘G-value paradox’ (‘G’ stands for ‘gene’), which directly concerns the discrepancy between the number of genes in an organism and its complexity (Hahn &amp; Wray 2002). This paradox has been reinforced by the findings of the HGP. As Gregory (2005) and other commentators have pointed out, the finding that the human genome contains many fewer genes than expected was one of the most surprising outcomes of the HGP. Initial estimates from before the project were in the range of 50,000 to 150,000. These were reduced to about 30,000—35,000 after the publication of the first sequence draft in 2001 and have now been further revised to the order of 20,000 (Gregory 2001).
