  1. GGP-50K SNPs from the GeneSeek Genomic Porcine 50K medium density genotyping array, LD Linkage disequilibrium, RNA-seq RNA sequencing, S1-S8 Scenarios 1 to 8. The percentage of RNA-seq and GGP-50K SNPs represents the proportion of SNPs from the pig transcriptome and from the GGP-50K in scenarios S4, S6, S7, and S8
