From: Analysis of transcriptome data reveals multifactor constraint on codon usage in Taenia multiceps
Neutrality plot analysis of the GC12 and GC3 values of the T. multiceps transcriptome. GC12 represents for the average value of GC-content in the first and second position of the codons (GC1 and GC2), while GC3 represents the GC-content in the third position. The red line shows the linear regression of GC12 against GC3, R 2 = 0.0348, P < 0.01. OP = 47.78, where OP is the intersection of the regression curve and the diagonal, and represents the point at which GC12 equals GC3
