Comments "As with transposable elements, it seems that the total abundance of pseudogenes (‘junk DNA’, properly defined) might correlate positively with genome size, although overall these elements constitute a relatively small fraction of genome size. For example, only 51 pseudogenes are found in the chicken genome (primary source 35), 14,000 in the mouse (primary source 31), 18,755 in the rat (primary source 36) and 19,000 in the human (primary source 46), in accordance with their rankings with respect to genome size."
