The relationship between effective population size (Ne) and the ratio AT→GC to GC → AT (β) estimated for homozygous (a) and heterozygous (b) SNVs present in individual genomes belonging to 126 distinct populations of the world. The data was obtained from the Simons Genome Variation Project. The correlation for homozygous SNVs was highly significant (P < 10− 6) but not statistically significant for heterozygous SNVs (P = 0.36). The colors represent populations from distinct geographical locations. The relationship shown in the inset was based on the estimates of Ne and β averaged for the populations belonging to a specific geographical location. The relationship shown in the inset was also significant (P < 0.026)
