What is the average size of a gene?

The average size of a vertebrate gene is about 30,000 base pairs. Bacteria, because their sequences contain only coding material, have smaller genes of about 1,000 base pairs each. Human genes are in the 20,000–50,000 base pairs range, although sizes greater than 100,000 have been suggested as well.
