Identifying SNPs associated with birth weight and days to 100 kg traits in Yorkshire pigs based on genotyping-by-sequencing

2020 
Abstract Birth weight (BW) and days to 100 kg (D100) are important economic traits that are both affected by polygenes. However, the genetic architecture of these quantitative traits is still elusive. Genotyping-by-sequencing (GBS) data containing a large number of single nucleotide polymorphisms (SNPs) have become a powerful tool in genomic analysis. To better understand their complex genetic structure, a total of 600 Yorkshire pigs were sequenced using GBS technology. After quality control, 279 787 SNPs were generated for subsequent genome-wide association study (GWAS). A total of 30 genome-wide SNPs (P
