Fig. 4From: Analysis of transcriptome data reveals multifactor constraint on codon usage in Taenia multiceps Distribution of effective number of codons (ENc) and GC3s of T. multiceps genes. The solid line (red) indicates the expected ENc value if the codon bias is only due to GC3s. The yellow squares, orange triangles and blue dots indicate ribosomal genes, essential genes and other genes, respectivelyBack to article page
