Fig. 4: Inference of relatedness based on pairwise relatedness estimates rxy and R0-R1 and KING-R1.
From: Kinship clustering within an ecologically diverse killer whale metapopulation
a Heatmap and adjacent dendrogram based on hierarchical clustering of pairwise relatedness estimates, rxy (data set 4: n = 169). Darker shades in the heatmap represent higher relatedness scores, with values ranging from 0 to 1. The diagonal, which depicts pairwise comparisons of each sample with itself, is omitted for clarity. Small subclusters along the diagonal were identified as family groups (data not shown). Individuals in the dendrogram are coloured according to their sampling location. b Schematic of a parent-offspring-trio (Supplementary Table S2), consisting of a juvenile with parents that have different dietary preferences (IS169 is a piscivorous male, IS253 is a female with a mixed diet). c Scatterplots of two combinations of relatedness metrics: R0-R1 and KING-R1. Previously known (n = 14) and inferred (n = 9) parent-offspring relationships are coloured in red. Inferred parent offspring relationships (n = 9) were only found within metapopulation demes (Supplementary Table S2). The two parent-offspring relationships in the trio are highlighted using black (IS253-J0610) and grey (IS169-J0610) arrows.
