Distribution of Pi, Theta, Fst and Tajima’s D values of 40 cultivated tomato accessions on reference tomato chromosomes. The gene density and Fst have been plotted in 1 Mb sliding window using Circos. Pi, Theta and Tajima’D have been plotted in 500-SNP sliding window with step size 100-SNP. Pi (Purple, min = −0.04, max = 0.04); Theta (Green, min = −0.04, max = 0.04); Tajima’s D (Red, min = −4, max = 4); Fst (Blue, min = −0.04, max = 0.04). Red and blue arrows denote the regions with Tajima’s D value −3 and below and the regions with Tajima’s D value 2 and above, respectively
