Distribution of SNPs after quality control on each chromosome.

aDerived from the most recent porcine genome sequence assembly (Sscrofa9.2) (http://www.ensembl.org/Sus_scrofa/Info/Index).bThese SNPs are not assigned to any chromosomes.a. 本数据集衍生自最新的猪基因组序列组装版本（Sscrofa9.2）（来源链接：http://www.ensembl.org/Sus_scrofa/Info/Index）。b. 本数据集中的单核苷酸多态性（Single Nucleotide Polymorphisms, SNPs）未被分配至任何染色体。
