Sliding-Window analyses of nucleotide diversity π and Tajima’s D in the association panel, with a sliding window size of 500 SNP markers and step intervals of 50 SNP markers on maize chromosome 2. Blue diamonds, π; Black diamonds, Tajima’s D; Red diamonds, windows containing the ZmIPT2 gene locus. Blue dashes represent the mean π value; Black dashes represent the mean Tajima’s D value.
