SNP distribution on the Clementine reference genome, using Scaffold_1as an example. Each interval of the x-axis represented500 kb of the scaffold, and the y-axis represented the number ofSNPs in each 500 kb on the scaffold. SO – sweet orange(A); TO – trifoliate orange (B); CM –Clementine mandarin (C); “_a” – counts of allalignments generated by all SNPs; “_1” – counts ofSNPs of only 1 unique hit/alignment in the genome. Differences betweenthe “_a” and “_1” numbers are observed inseveral regions of each cultivar.
