Significance plot of SNPs in the candidate region (15.8–16.1 Mbp on BTA7) and their gene locations. The plot shows the distribution of all the SNPs located in the candidate regions. The x-axis indicates chromosome 7 positions in Mbp and the y-axis indicates log–inverse p-values. The blue circles indicate 76 SNPs that were previously identified in the candidate region (Sasazaki et al., 2022). The red and yellow circles indicate 13 candidate SNPs responsible for beef marbling identified in this study
