Association of SNPs with vertebral number, and linkage disequilibrium analysis. In the 450-kb region around the QTL, SNPs were developed and were genotyped by using 199 independent meat animals, for which the numbers of vertebrae were scored. The associations between SNPs and numbers of vertebrae are presented, with F-values. Linkage disequilibrium was analyzed by using Haploview software, and the R2 values are presented in the boxes. For the two gray intervals in the graph, SNPs (minor allele frequency > 0.01) were not detected in our DNA samples from European breed pigs.
