Fig. 1: Analyses of the relationship among aggressive, tame and conventional red fox populations.
From: Red fox genome assembly identifies genomic regions associated with tame and aggressive behaviours
a–c, PCA (a), neighbour-joining tree analysis (b) and STRUCTURE analysis (c) of the fox populations. All analyses were performed using SNP data for 30 foxes (10 each from the tame, aggressive and conventional populations) whose genomes were re-sequenced. In a and b, each individual is represented by a data point. In c, each individual is represented by a bar that is segmented into colours based on its assignment into inferred clusters given the assumption of k populations. The length of the coloured segment is the estimated proportion of the individual’s genome belonging to that cluster. Each level of k was run four times, but the data shown are from the run giving the highest estimated probability of observing the data. The assumed number of clusters (k) is indicated on the y-axis. The population origin of individuals is indicated on the x-axis.
