Figure 4

Frequencies of SNPs (y-axis) occurring in each dinucleotide context (x-axis) compiled from approximately 45 million SNPs in human genomic DNA sequences. These were categorised by mutation type and by the base downstream of the SNP (3′ dinucleotide context). Frequencies of SNPs were normalised to those predicted from dinucleotide frequencies and transition and transversion rates measured in the whole SNP dataset.
