High concordance between SNPs identified by the porcine 60K BeadChip genotyping array (Illumina) and the assembly-versus-assembly method. Sus scrofa

Porcine 60K BeadChip genotyping arrays (Illumina) are increasingly being applied in pig genomics to validate SNPs identified by re-sequencing or assembly-versus-assembly method. Here we report that more than 98% SNPs identified from the porcine 60K BeadChip genotyping array (Illumina) were consistent with the SNPs identified from the assembly-based method. This result demonstrates that whole-genome de novo assembly is a reliable approach to deriving accurate maps of SNPs. Overall design: To compare SNPs identified by genotyping arrays and de novo assembly method, we genotyped 10 pig breeds by porcine 60K BeadChip genotyping array (Illumina), including 1 berkshire pig, 1 hampshire pig, 1 landrace pig, 1 large white pig,1 piétrain pig, 1 bamei pig,1 jinhua pig, 1 meishan pig, 1 rongchang pig and 1 Tibetan wild boar.
