Fig. 4From: Design of experiments for fine-mapping quantitative trait loci in livestock populationsEmpirical bovine HD SNP chip data. a Correlation matrix for a randomly selected window containing 300 SNPs on BTA7. b Violinplot of nopt vs. number of QTL signals to be detected. The diamond indicates the median of nopt and the blue dots mark the results based on a single-SNP model, N=10 and h2=0.1Back to article page
