Figure 4From: Simple sequence repeats in Neurospora crassa: distribution, polymorphism and evolutionary inferenceThe distributions of the repeat lengths of the different types of amino acid repeats encoded by tri-nucleotide SSRs. The x-axis represents the length of amino acid repeat and the primary y-axis (left side) is the observed count of individual amino acid repeats in a given amino acid motif (thin lines) and the secondary y-axis (right side) is the observed count of all amino acid repeats combined (thick red line).Back to article page
