Table 1. Genotype information for the studied population

	Number of animal	Original genotype	SNPs removed by QC			Number of SNPs after QC
			Not located or located on sex chromosome	Minor allele frequency (< 0.011))	Missing genotype (> 0.12))
Berkshire (BS)	695	63149	11,166	359	10,030	41,594
Korean native × Landrace crossbreed (CB)	594	49255	4,214	5,606	433	39,002

Alleles removed when minor allele frequency < 1%.
Alleles removed when genotype is missing from > 10% of the entire population.
SNPs, single nucleotide polymorphisms; QC, quality control.
