Figure 5From: SNiPlay: a web-based tool for detection, management and analysis of SNPs. Application to grapevine diversity projectsDiversity map. Tajima's values are color-coded along the chromosomes. A normal distribution of Tajima's values is assumed to estimate significance: significantly negative values (in red; p < 0.05) suggest an excess of low frequency SNPs, indicating putative regions under purifying selection, while high values (in green) indicate regions where diversification probably occurred.Back to article page
