名詞 定義 
cladogram A cladogram is a special phylogenetic tree, usually with implied ancestry based on shared derived characters, and with a relative time axis, also: a dendrogram or tree-like diagram expressing the evolutionary relationships among a group of organisms in terms of recency of common ancestra or descent. All taxa are terminal in position, the identity of nodes (ancestors) are not specified and connecting lines represent shared derived characters (synapomorphies). Any two branch tips sharing the same immediate node are most closely related. A cladogram only specifies the relative degrees of phylogenetic relationship (sistergroup relationships) of the analysed taxa, as well as their monophyly.  
支序圖、枝狀圖 是利用多個分類群特徵或遺傳訊息之異同所建構的枝狀圖, 某一分類群在分支圖中的位置,可反映出其在此分類群組中的特殊性,及與其他分類群的關係。透過系統發育分支圖的建立,可估計圖中某幾個分類群集合體所帶有的特徵多樣性。
