- supply hybrid species 提供杂交种
- Homoploid hybrid species are easily recreated in the greenhouse, perhaps explaining why many are multiply derived in the wild. 同倍杂合体物种在温室很容易再生,这也许能解释为什么在野生环境中有很多起源。
- In contrast to homoploid hybrid species,polyploid species are easily diagnosed because of chromosome number changes associated with genome doubling. 与同倍杂合体物种相比,因为与基因组加倍相关的染色体数目的变化,多倍杂合体物种很容易判断。
- Among the three hybrid species, the AACC and BBCC genomes are the closest Genetically, the AABB genome has a longer distance from the BB genome man from the AA genome. 复合种同基本种之间的关系是:AABB和AA基因组的关系,要比它同BB的关系近,BBCC同CC基因组的关系,要比它同BB基因组近。
- As hypothesized, all plant homoploid hybrid species are ecologically diverged and exhibit some degree of ecogeographic isolation, and roughly half have differing karyotypes . 据推测,所有植物同倍杂合体物种都被生态学分离,而且展现出一定程度的生态地理隔离,大约有一半的具有不同的核型。
- Fully isolated polyploid species may arise in one or two generations, and diploid or homoploid hybrid species may achieve isolation in as few as 60 generations (13). 完全隔离的多倍体物种可能在一两代内出现,而二倍体或者同倍体杂种经过六十代后可能获得隔离(13)。
- Homoploid hybrid species may become reproductively isolated by rapid karyotypic evolution, ecological divergence, and spatial isolation of the new hybrid lineage. 由于新的杂交世代迅速的核型演化,生态差异和空间隔离,同倍杂合体物种可能形成生殖隔离。
- In addition to these biological difficulties, homoploid hybrid species are technically challenging to detect because they often lack diagnostic features, such as a change in chromosome number. 另外,同倍杂合体物种在技术上不易检测,因为他们很多都缺乏诊断的特性,例如染色体数目的变化。

- The fusing of religious and political spheres under Islam has produced a hybrid species of faith-based public intellectual scarcely seen in America, where faith speaks the vernacular of populism. 在伊斯兰社会政教合一的环境下,产生了一种以信仰为基础的混合型公共知识分子。在宗教人员需要用本地方言来传教的美国,这种情况是不会出现的。
- Karyotypic divergence and spatial isolation both reduce the probability that hybrid species will be generated but will enhance the evolutionary independence of hybrid lineages once they arise. 核型分离和空间隔离都会减小杂合物种的形成,但是一旦他们形成后就会促进杂合体世代的进化独立性。
- Meanwhile, had principium exploration on tissue culture system of fodder beet, all these works were purpose to provide pure parent materials with tissue culture for excellent triploid hybrid species. 同时还对饲用甜菜组织培养再生体系的建立进行了初步探索,旨在利用组培快繁技术为优良三倍体杂交种提供纯合的亲本材料。
- First, homoploid hybrid species have strongly reduced fitness in early generation hybrids as selection eliminates incompatibilities. 相比之下,多倍体物种不需要在中间阶段降低育性。

- Our country has a bountiful supply of food. 我们国家有充足的食物供应。
- In addition, we supply small parts for replacement. 此外,我们还提供备用小零件。
