Distribution of codon diversities of the long homopolymers (⩾20 repeats) from D. discoideum. The D values (y-axis) are plotted against the length of homopolymers (x-axis) with a different color and symbol for each amino acid (n=3391). The two unusually long (>100 repeats) homopolymers poly-S₃₀₆ and poly-S₁₃₂ are identified.
