Fig. 2From: Evaluating the accuracy of genomic prediction of growth and wood traits in two Eucalyptus species and their F1 hybridsGenetic structure and relatedness in the breeding population. (a) First two principal components of a PCA revealing population structure. Dots represent E.grandis (blue), E.urophylla (red) and their F1 (green) individuals. (b) Heatmaps of the pairwise pedigree-expected relationships (blue, upper off-diagonal) and genomic-realized relationship (red, lower off-diagonal) of the 1117 individuals assigned to E.grandis (G), E.urophylla (U) and their hybrid progenies (H)Back to article page
