Figure 4From: QTL analyses of temporal and intensity components of home-cage activity in KJR and C57BL/6J strainsFinal path illustrations obtained by structural equation model analysis (SEM). SEM analysis of two components, AA and AT, of spontaneous home-cage activity. e1 and e2 indicate the unobserved residual error. D4Mit288 is a locus which showed no significant LOD acore in the IM analysis. A curved arrow indicate genetic linkage between two loci.Back to article page
