Figure 7

(A) The ENc vs. GC3s plots of Oestroidean mitochondrial protein-coding genes. The standard curve ENc = 2 + GC3s + 29/[GC3s2 + (1 − GC3s)2] represents the expected ENc to GC3s. (B) Neutrality plots (GC12 vs. GC3) of 13 PCGs of 42 species. GC12 stands for the average value of GC content in the first and second position of the codons (GC1 and GC2). While GC3 refers to the GC content in the third codon position (each dot signifying a gene). (C) Probability of selection pressure on each PCGs of Oestroidea. The regression line of all PCGs denoted by y = mx + c (Where, Mutational Pressure (M) = m * 100, Natural Selection (N) = 100 − M).
