The human genome density ranges between 12-15 genes per Megabase pairs. This is because humans have approximately 2000 genes in a total of approximately 3 billion base pairs. However, some primitive organisms have an even larger gene density
than humans. An example is bacteria with gene densities ranging between 100 –
500 genes/Mb. Gene density is therefore
not a good characteristic in determining
the complexity of an organism.
