PolyAna (available at http://www.biol.sc.edu/~austin/) aids in the analysis of natural selection on protein-coding sequences by estimating sample gene diversity at individual polymorphic nucleotide sites, which are classified as synonymous, non-synonymous, or ambiguous.

PolyAna：分析同义和非同义多态站点。

PolyAna（可从 http://www.biol.sc.edu/~austin/ 获得）通过估计单个多态性核苷酸位点的样本基因多样性，帮助分析蛋白质编码序列的自然选择，这些位点被归类为同义、非-同义的，或模棱两可的。
