Fig. 1From: Design of experiments for fine-mapping quantitative trait loci in livestock populationsDistribution of optimal sample size. Violinplot of nopt vs. number of half-sib families for different numbers of QTL signals in a multi-SNP model. The parent generation was simulated 100 times and 100 random draws of positions of QTL signals were analyzed in each run, h2=0.1. The diamond indicates the median of nopt and the blue line marks the results based on a single-SNP modelBack to article page
