Performance of Δ JC and ΔK 2P on a series of quartets of type B. A series of homogeneous K2P quartets is considered (left illustration), with ti-tv ratio of R =5, and edge lengths t i =0.2, t l =1, and t s [0.2,1]. (a) Reconstruction accuracy using FPM and either ΔJC (dashed green) or ΔK2P (solid red) plotted against t l /t s . Accuracy ratio is estimated using 100,000 independent replicates for each value of t s in the interval [0.2,1] (in steps of 0.01), with sequence length 1,000 bp. (b) Fisher’s Criterion (FC) for the sums corresponding to splits (12|34) and (13|24) under either ΔJC (dashed green) or ΔK2P (solid red) plotted against t l /t s .
