SNP Density
Human = ~1.18 SNPs per kbases
Based on CgsSNP, the average numbers of SNPs per 10 kb was 8.33, 8.44,
and 8.09 in the human genome, in intergenic regions, and in genic
regions, respectively.

Drosophila melanogaster = ~0.02 SNP per kbases
FLYSNPdb provides high-resolution single nucleotide polymorphism (SNP)
data of Drosophila melanogaster. The database currently contains 27
367 polymorphisms, including >3700 indels (insertions/deletions),
covering all major chromsomes. These SNPs are clustered into 2238
markers, which are evenly distributed with an average density of one
marker every 50.3 kb or 6.6 genes.
