Figure 4

Imbalance of human gene family trees. Imbalance of human gene family trees against number of leaves, comparing values for the four different sets of gene family trees used here. (a) Mean Im values of human gene families for each leaf number, with bars representing 2 standard errors. Lines connect 10-term moving averages of Im values. (b-d) Comparison of imbalance, measured by Colless's Im, between human gene family phylogenies (shown as black triangular points) with species phylogenies. (b) Species phylogenies from Heard [31, light gray, unbroken line, star-shaped points] and Mooers [10, mid gray, dashed line, diamond-shaped points]. (c) Morphological phylogenies from Harcourt-Brown [30, mid gray, dashed line, diamond-shaped points] and molecular phylogenies from Harcourt-Brown [29, light gray, dotted line, star-shaped points]. (d) Species phylogenies from Stam [28, unbroken gray line, diamond-shaped points]. Smooth lines on all figures connect expected mean Im values under the ERM (lower, solid line) and PDA models (upper, dashed line).
