遗传地

Telegony is a theory in heredity, now discredited but widely believed until the late 19th century, holding that offspring can inherit the characteristics of a previous mate of one or both parents.

先父遗传是一种遗传上的理论，现今它被证明不真实，但是直到19世纪晚期，它还广泛地被相信和接受。这个理论是说，后代能继承父母双方中一方的前任伴侣的特徵。

Telegony is a theory in heredity , now discredited but widely believed until the late 19th century, holding that offspring can inherit the characteristics of a previous mate of the female parent; thus the child of a widowed or remarried woman might partake of traits of a previous husband.

先父遗传是一种遗传上的理论，现今它被证明不真实，但是直到19世纪晚期，它还广泛地被相信和接受。这个理论是说，后代能继承父母双方中一方的前任伴侣的特征，因此寡妇或再婚女人的子女会有她们前任丈夫的部分特征。

However, the results also showed that these drought-resistant varieties have quite different genetic diversity, which can provide a theoretical basis for using these variety resources in wheat or triticale's draught-resistant breeding.

但反过来可以说明这些抗旱性强的品种其遗传差异较大，遗传变异丰富，为在小麦或小黑麦的抗旱育种中更好地利用这些品种资源提供了依据。

This is a new approach to determine optimal flow distribution of pipe segment and water source.

提出了环状管网优化设计的遗传-线性规划算法，将遗传算法和线性规划有机的结合在一起，是一种有效地解决环状管网优化设计问题的新方法。

Shanghai Agrobiological Gene Center research subject: 1、 Adhering to the principle of keeping genetic diversity to the maximum extent, collect, appraise and keep the agricultural biological gene resource which was originally stored in Shanghai; Give priority to what is the most important, collect good resources with important scientific significance and economic value as well as application value at global range

上海市农业生物基因中心的主要研究内容：1、本着最大限度地保存遗传多样性的原则，广泛收集鉴定保存原产于上海市的农业生物基因资源；突出重点，全球范围内收集具有重要科学意义与经济价值或应用前景的优良资源；2、建立主要农作物功能基因组研究的资源平台；积极开展遗传材料的创制；发展种质资源保存与评价的技术方法；3、种质资源的综合评价与深入研究，鉴定、定位和克隆具有自主知识产权的重要农业生物基因； 4、进行植物新品种保护的研究；全国范围内分发与有效利用种质资源。

Apparently, the giant panda's evolution from Ursus to Ailuropoda required the change of only a few genetic messages (5 or 6 perhaps), yet the phenotypic and lifestyle change from a standard bear is considerable. The transition could therefore be effected relatively swiftly.

显然，从熊到大熊猫的进化只需要少数遗传信息（也许5或6个遗传信息）的改变；然而，在表型和生活方式上与一头标准熊相比，发生了相当大的改变；而且这种转变过渡可能是相对迅速地达到的。

This whole research constitutes two independent projects, that is "Estimating divergence times among subfamilies in Nymphalidae" and "Fine- and landscape-scale spatial genetic structure of cushion rockjasmine, Androsace tapete, across southern Qinghai-Tibetan Plateau", which discussed respectively the application of molecular evolutionary analysis in two aspects of evolutionary biology.

分子进化分析就是利用分子数据来研究进化问题。地球上呈现的生物多样性则是突变和自然选择的产物，是生物进化的结果。生物进化的过程包含有两个面：基因的长期进化和遗传多样性，也就是通常意义上的大进化和小进化。该项目就是以两个不同的实验——即&蛱蝶科各亚科间分歧时间的估计&和&青藏高原垫状点地梅的空间遗传结构分析&——分别探讨了分子进化分析在大小进化两个方面的应用。
