From: Population size influences the type of nucleotide variations in humans
Relationship between the effective population size (Ne) and the ratio of AT→GC to GC → AT (β) changes. The genotype data was obtained for 27 populations of the world. The colors indicate different geographical locations of the populations. The relationship was not significant for SNVs with DAF < 0.025 (P = 0.11, using the Spearman rank correlation) but highly significant for those with DAF > 0.9 (P < 10− 6). Nucleotide substitutions (SNVs with DAF =1) were excluded
