Figure 3: The regression model of human ID1 variant1, human ID1 variant2, and chimp ID1. The -axis represents di-nucleotide entropy in bits per symbol, and -axis presents the fractal dimension. The graph scale is kept identical to that of Figures 1 and 2 for easy comparison. The CDS sequence (diamond) regression has of 0.991 and an adjusted of 0.983 (the chimp has the highest fractal dimension). The mRNA (square) sequence regression has of 0.924 (the chimp is in the middle among the three data points).
