Tajima’s D and FST plot of positively selected gene regions in Sanga and indicus cattle populations. a CAPZB gene; b PKM2 gene; c PDGFRA gene; d AHSA1 gene; and e MB gene. For other genes, please see Additional file 6: Figure S1. The Tajima’s D plot for each gene region (upper plot for each gene) show the Tajima’s D value within a 50 kb window plotted for both populations. The smaller (negative) Tajima’s D value in the Sanga population shows that the gene region considered is under positive selection. The FST plot (lower plot for each gene) represents the FST values calculated within 50 kb windows separated by 5 kb window steps
