From: Analysis of codon usage patterns in Hirudinaria manillensis reveals a preference for GC-ending codons caused by dominant selection constraints

Base composition of H. manillensis. a Distribution of CDSs with different GC content levels in of H. manillensis; (b) Box plot indicates GC content variation in different codon positions (1st, 2nd and 3rd represent the first, second and third codon position, respectively) and overall genome (All). c Dinucleotide frequency plot in different combination of different codon positions (1st&2nd, 2nd&3rd and 3rd&1st) and overall genome (All), unbiased frequency means the theoretical frequency when all dinucleotides were presented equal, the curve located at 0.0625 (1/16)
