Likelihood ratio test (LRT) for significance of autosomal heritability or proportion of phenotypic variance explained for androstenone using three different linear mixed models. LRTind is comparing a model fitting an individual autosome with a null model, LRTdrop is where all autosomes are fitted and compared with a model which drops each autosome in turn, LRTpoly is comparing a model fitting an individual autosome plus a polygenic effect with a model containing only a polygenic effect.
