Figure 4. The genetic architecture of parental behaviour.

Figure 4

a) Correlation matrix of parental behaviours in F2 hybrids. b) The linkage (lod score) of each behaviour to each marker in each sex and the sex-by-genotype interaction (gray). Boxes delineate the Bayes 0.95 credible interval of QTL of genome-wide significance (α=0.05). Dots denote the allele at the peak of the QTL that correlates with a higher value for that behaviour (for handling and approach, a decrease in latency to perform behaviour). Heterozygotes at QTLs on chromosomes 2 and 12 (females only) retrieve more pups (see Extended Data Fig. 4 and Supplementary Discussion).
