Figure 1

Genomewide distribution of genetic variation and differentiation across three populations using 31,119 SNPs. Populations are represented as dark green (RS), purple (ZS) and red (FA) blocks respectively in a circle. The expected heterozygosity H e (blue line), nucleotide diversity π (purple line) and Tajima’s D value (yellow line) are plotted as functions of genomic position with a non-overlapping 100-bp sliding window.
