多倍性

Polyploidy and autogamy are important evolutionary phenomena within the genus.

多倍性和自花受精为本属的重要的进化的现象。

We presumed that the term of Y-linked inheritance cannot confuse with that of sex-limited inheritance, and that though the sex-limited factor and the sex-influenced inheritance gene are both located on autosome with some distance, but they are still different.

对现行的遗传学教材中存在的专业术语同名异义现象进行探研，针对Y连锁遗传、限性遗传、从性遗传、单倍体、多倍性和累加作用等专业术语存在的表达不清，相互矛盾，同名异义等问题，进行分析探讨，并提出Y连锁遗传不能与限性遗传相混淆，限性遗传和从性遗传的基因是位于常染色体上，但二者存在区别。

Polyploidy is observed in many species of both plants and animals.

在植物和动物中都观察到许多物种的多倍性。

In plants, polyploidy must be included in any view of speciation.

在植物中，任何物种形成观念都必须考虑多倍性。

Chromosome number also gives an indication of polyploidy, where numbers vary by exact multiples between related species.

当多倍性现象发生时，物种的染色体数目是原来的整数倍。

The phenomenon of polyploidy and aneuploidy exists in the Genus, in which there are polyploid complex.

对19个分类群作了核型观察，其中16个分类群作了组型分析，结果表明各分类群间核型差异显著，该属普遍存在着多倍性和非整倍性现象，并有多倍体复合体类群存在。

Polyploidy is a mechanism often attributed to causing some speciation events in sympatry.

多倍性常被当作引起在同一地区并存的物种发生物种形成事件的一种机制。

Autopolyploidy A type of polyploidy involving the multiplication of chromo-some sets from only one species.

同源多倍性：通常是由同一个体，同一纯种的染色体数目加倍而成的多倍性现象。

Firstly, an invasive species must be invasive enough in itself or has some biological distinction, such as quantitative and qualitative differences in the genome, or patterns of recombination. Secondly, to invade successfully, a new environment for an invasive species must be invasible, and this we may call the ecological basis of invasion. An invasive species may need to establish new interactions with other species, especially those mutualistic relations such as animal related pollination, seed dispersal by animals, mycorrhizal fungi, and symbioses between plants and nitrogen fixing bacteria.

首先从其自身来说，需要有足够的入侵性，这可以认为是入侵种的生物学基础，可能表现为具有多倍性、一定的遗传变异、杂合性或表型可塑性，以及不同的交配系统等；其次一个物种的入侵成功还取决于入侵生境的可入侵性，这可以认为是入侵种的生态学基础，而新的种间关系的形成，尤其是入侵种与其他种类的互惠共生关系的建成是关键。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
