Visualization of genetic distance matrix K. Left: Heatmap of K, where lighter colours indicate higher genetic similarity between individuals. (P, parents; An × Am, cross between AG n and AG m; Cn, cross n). Right: Individual genotypes plotted on the two first principal components of the K matrix. Dot clouds correspond to offspring of crosses 1–9 (X, central parent, of AG1; A, peripheral parents of AG1; B, peripheral parents of AG2; C, peripheral parents of AG3)
