Schematic representation of the filters applied to design the Axiom™ Pear 700 K Genotyping Array. The diagram on the left-hand side shows the different steps of the Quality filter, the Affymetrix filter and the SNP selection applied through the pathway from the initial number of new variants discovered to the final set of SNPs tiled on the Axiom Pear 700 K Genotyping Array. The diagram on the right-hand side shows the Affymetrix filtering steps applied to the validated SNPs prior to inclusion in the Axiom Pear 700 K Genotyping Array. The total number of variants at each step are reported
