From: Disentangling clustering configuration intricacies for divergently selected chicken breeds
Cluster analysis for distribution of the 11 core breeds using the k-means (A) and elbow (B) methods. Breed (sub)types (A): 1, egg type (cluster-2); 2, egg-meat subtype (cluster-1); 3, meat-egg subtype (cluster-0); and 4, meat type (cluster-3). Optimal number of clusters (k) was 4 (B). EY/W, integral performance index as a ratio of egg mass yield (EY) and female body weight (W).
