Fig. 2From: Parsing the synonymous mutations in the maize genome: isoaccepting mutations are more advantageous in regions with codon co-occurrence biasPipeline of the process of defining types of mutations. Each mutation in the CDS must belong to one of three categories: isoaccepting, nonisoaccepting or nonsynonymous (if nonsense mutations are not considered). The relationship is determined by the codon after the mutation versus the codon before the mutation. For each mutation, the minor allele frequency (MAF) is then calculatedBack to article page
