a
Among the 62,163 SNPs in the Illumina Porcine 64k SNP beadchip, each SNP was selected for whole genome association (WGA) tests if the number of genotype group is two or three, the minor allele frequency was greater than 0.05, and proportion of genotyped individuals was greater than 90%.
b
The distances between the first and the last SNPs that were located on their respective chromosomes.
