n.遺傳分類學(xué)

The phylogeny of the known 427 genera of Tenthredinoidea of world was reconstructed using the principle and methods of cladistics. 應(yīng)用支序系統(tǒng)學(xué)原理和方法研究了膜翅目葉蜂總科世界已知427屬的系統(tǒng)發(fā)育關(guān)系。

In cladist ic analysis, the genera of Disporum, Maianthemum and Disporopsis of Po lygonateae were chosen as complex outgroups. 在分支分析中，選擇萬壽竹屬、舞鶴草屬和竹根七屬作為復(fù)合外類群。根據(jù)復(fù)合外類群比較原則和一般演化規(guī)律，確定性狀極性。

Cladistics A method of classification in which the relationships between organisms are based on selected shared characteristics. 遺傳分類學(xué)：生物體之間關(guān)系建立在有選擇的性狀上的分類方法。

Based on the principles and methods of cladistics, the phylogeny in Kengyilia of Poaceae is analysed in the present paper.Kengyilia is a monophyletic group. 摘要基于分支系統(tǒng)學(xué)的原理和方法，對(duì)禾本科以禮草屬進(jìn)行了系統(tǒng)發(fā)育分析。

Compare cladistics. 比較cladistics。
