Figure 3From: Phylogeny and virulence divergency analyses of Toxoplasma gondii isolates from ChinaDetermination of the optimal K value among worldwide T. gondii isolates. The calculating formula of L (K) (A), L’(K) (B), | L”(K) | (C) and ΔK (D) were identical to Figure 1A. From the diagram of delta K, the most true value of clusters is 4.Back to article page
