A) Functional and further details about the genes within the OspIge5.1 QTL for B6 maternal behaviour on day 14, obtained from GeneNetwork, Entrez genes, and Mouse Genome Informatics. Potential candidate genes in this region are Cyp3a16, Cyp3a44, Cyp3a11, Cyp3a25 and Cyp3a41a because of their involvement in steroid hormone biosynthesis. B) Functional and further details about the genes within the MatDge1.1 QTL for BXD nestbuilding on day 6, obtained from GeneNetwork, Entrez genes, and Mouse Genome Informatics. Potential candidate genes in this region include: Hsd17b7, as it is involved in steroid hormone synthesis, and hormonal regulation is needed to initiate nestbuilding behaviour (Gammie et al., 2007; Keisala et al., 2007; Bester-Meredith and Marler, 2012); Pou2f1, Lmx1a and Rgs4 as they are linked to activity related phenotypes; finally, Pbx1 and Ddr2 have been linked to craniofacial morphology, which may affect the ability to make nests (Schneider et al., 2012). C) Functional and further details about the genes within the MatDge10.1 QTL for BXD maternal behaviour on day 6, obtained from GeneNetwork, Entrez genes, and Mouse Genome Informatics. A potential candidate gene is Ifngr1 as it is related to depression-like behaviour, which in turn has been linked to reduced maternal care (Smith et al., 2004; Malkesman et al., 2008). D) Functional and further details about the genes within the OspDge5.1 QTL for BXD offspring solicitation on day 6, obtained from GeneNetwork, Entrez genes, and Mouse Genome Informatics. Cdk5 might be a good candidate as it is involved in several neuronal annotations (e.g. axonogenesis and synaptic transmission), and mutants have no suckling reflex (Ohshima et al., 1996).
