Figure 2From: Inferring evolution of gene duplicates using probabilistic models and nonparametric belief propagationThere are two cases ( B ) and ( C ) after normalizing by the maximum value max( x, a, b ) in ( A ). In (B), the maximum value is x = 1 after normalization. SF is defined by a + b = 1. In (C), the maximum value is b = 1 after normalization. CF and NF are defined by 1 + a = 2x and x = a, x ≤ 0.5, respectively.Back to article page
