Fig. 7From: Analysis of codon usage bias of envelope glycoprotein genes in nuclear polyhedrosis virus (NPV) and its relation to evolutionNeutrality plot analysis of the 18 glycoprotein genes. Neutrality plot analysis of the average GC content in the first and second positions of the codons (GC1 and GC2) and of the GC content in the third position (GC3) for glycoprotein. The blue, purple and yellow regression curve represented as y = 0.1063x + 34.14, R2 = 0.4307, y = 0.0685x + 37.15, R2 = 0.3517, y = 0.0956x + 34.02, R2 = 0.5645. The diagonal line is colored in red dotted line Back to article page
