Positive selection in MSG genes. MSG genes were aligned and the frequency of non synonymous (abbreviated Non syn) and synonymous (Syn) substitutions as well as INDELS was scored for each codon. The horizontal lines labeled HV1 etc, demarcate five hypervariable regions. The horizontal lines labeled CR and C1 demarcate constant regions CRJE and C1.
