The major agronomic characters, morphology and the genetic stability of polyembryonic seedling of the mutant line were systematically investigated. The results are as follows. The agronomic characters of IR36-Shuang were obvious different with its parent IR36-4X. The plant height, panicle length, 1000 grain weight and the setting rate of the IR36-Shuang were lower than that of its parent by 35.41%、5.08%、15.72% and 12.39%, respectively.

对该突变株后代的主要农艺性状、多胚苗形态特征和遗传稳定性进行研究表明，突变株系与其原始亲本在主要农艺性状上存在明显差异，前者在株高、穗长、千粒重和结实率等性状上比后者分别下降35.41%、5.08%、15.72%和12.39%。

Occurrence records from 1864 locations and 34 environmental variables from Daymet datasets were gathered, four modeling methods including Logistic Regression, Classification and Regression Trees, Genetic Algorithm for Rule-Set Prediction and maximum entropy method were used to generate potential geographic distributions for Dreissena polymorpha in the continental USA. Then three statistical criteria including area under the Receiver Operating Characteristic curve, correlation and Kappa were calculated to evaluate the performance of the models, followed by analyses of major variable contributions.

论文以1864个美国外来入侵物种斑马纹贻贝定点发生数据和开放式基础地理信息数据库Daymet的34个环境变量为主要信息源，采用逻辑斯蒂回归、分类与回归树模型、基于规则的遗传算法、最大熵法4种途径，建立美国大陆部分潜在生境预测模型，从接受者运行特征曲线下面积、Pearson相关系数、Kappa值3个方面来检验模型预测精度，在此基础上分析斑马纹贻贝的空间分布规律及其环境影响因素。

Morphological traits and living habit of Tibetan chicken, which is an aboriginal chicken breed on plateau with its own characteristic populational genetic features, are in great common with the Red Jungle Fowl, the assumed ancestry of domestic chicken.

为了有效保护并合理利用这一遗传资源，我们采用多重PCR与半自动荧光标记微卫星聚丙烯酰胺凝胶电泳相结合的方法检测了20个微卫星基因座的多态性，并随机抽取藏鸡群体中部分个体进行个体体形特征与生产性能的统计。

More speculatively, important human traits like leadership, genius in its many manifestations, being an effective therapist or parent, as well as certain psychopathological syndromes may also be emergenic.

更不确定的是，重要的个人特征，如领导能力，在许多表现形式上的天份，成为极为出色的治疗专家或家长；同时，某些精神病理学综合症状，也可能出现遗传。

The reappearance of a characteristic in an organism after several generations of absence,usually caused by the chance recomb in ation of genes.

返祖现象，隔代遗传机体特征在几代缺失后重新出现，通常由基因重组引起

The mechanism of triploid seedlessness, evaluation approaches of triploid grapes and embryo rescue technique are also discussed. Seven newly bred triploid seedless cultivars in the world are briefly described such as Yileyi, King Dela, Honey Seedless, Kai Mi...
