Fig. 2: Features of the PeachSNP170K array.

a The distribution of SNPs across the peach genome: (i) all eight peach chromosomes, (ii) publicly available QTLs and associated SNPs (Supplementary Data 10), (iii) SNP density in a 100 kb window for the PeachSNP170K array, (iv) SNP density for IPSC peach 9 K SNP array, and (v) gene density in a 100 kb window. b Physical interval distribution between SNP sites on the PeachSNP170K array, showing that over 90% of the intervals are below 3,096 bp. Red curve: interval number; blue curve: accumulated percentage of interval number. c Categorization of SNPs into genic, intergenic, upstream, downstream, and upstream/downstream regions, based on reference genome annotation.
