Fixation index (F ST ) for E. melliodora and E. sideroxylon.SNP datasets were combined for each reference genome, and subsequently F ST was calculated for each SNP using PLINK [65]
Principal component analysis (PCA) of E. melliodora and E. sideroxylon.SNPs for both populations were called using both reference genomes. Merging all SNPs for the E. melliodora reference, PCA was per
