Hexaploid wheat has a lot of homoelogous gones in its genomes, and the main objective of wheat breeding is to get good phenotypes.

小麦是异源六倍体,其染色体组中存在着大量的同源基因,其育种的主要目标是获得可遗传的优良性状。

In the first part, the concepts of the completely normal spaces and strong completely normal spaces in L-topological spaces are defined, which are the generalization of the completely normal spaces in general topological spaces. They are some good properties such as hereditary, weakly homeomorphism invariant properties, good L-extension, but they arent producible in general.

第一部分的主要内容如下:第一部分这一部分是将一般拓扑学的完全正规分离性的概念推广到了L-拓扑空间,给出了L-拓扑空间的完全正规分离性和强完全正规分离性的定义并讨论了它们的若干性质,比如,它们都是可遗传的,弱同胚不变的,"Lowen意义下好的推广"等。

Huntington's disease is an inherited disease causing the death of dopamine-producing cells in the brain.

亨廷顿氏病是一种可以导致大脑中产生多巴胺的细胞死亡的,可遗传的疾病。

Optimal algorithm of combined nonlinear Hopfield network appears powerful validity in solving nonlinear planning, which includes nonlinear objective function, linear constrains and high-demension of decision-making variants, for its ability of nonlinear parallel computation. It is prominent among optimal algorithms because of its function of simply implement with electrocircuit hardware. Genetic algorithm is expressly suitable for optimal calculation regarding the planning of massive, highly nonlinear, inconsecutively differentiable and multiobjective function as well as objective function without analytical expression. However, it inclines to prematurity, as well as its limitation in ability of partial optimal search. Introducing the optimal algorithm of niche genetic simulated annealing to standard Genetic algorithm, can therefore improve the full-scale or partial search ability of Genetic algorithm effectively. It has a far-flung perspective in the field of systemic planning of water pollution control.

组合式非线性Hopfield网络优化算法所具有的非线性大规模并行计算能力在求解具有非线性目标函数、线性约束条件及高维决策变量的非线性规划问题方面显示出了强大的生命力,它易于电路硬件实现的功能更是在优化算法中独树一帜;遗传算法采用概率搜索技术,不受目标函数与约束条件的限制,特别适合大规模、高度非线性的不连续可微的多峰目标函数及无解析表达式的目标函数的规划问题的优化计算,但其存在容易早熟、局部寻优能力较差等缺点,本文在标准遗传算法中引入小生境技术及模拟退火算法有效地改善遗传算法的全局和局部搜索性能,提高了全局最优解的寻优质量,小生境遗传退火模拟优化算法在水污染控制系统规划中的应用前景极为广阔。

The individuals that survive are most likely to leave their inheritable traits to future generations.

那些生存下来的个体有比较大的机会将那些可遗传的性状传给后代。

It is also proved that the class of monotone increase functions is PAC solvable under a GA with reproduction and random mutation.

本文还证明了对于由复制和一个按顺序的变异构成的遗传算法,严格单增的函数是PAC可解的,单峰函数是非PAC可解的;对于由复制和随机变异构成的遗传算法,严格单增函数是PAC可解的。

The origin of an organism 's inheritable body, or morphogenesis, is due then to a partnership of nongenetic cell material and hereditary genes -- body and genes.

那么,有机体的可遗传肉体,或者说它的形态形成的根源就归因于非遗传的细胞物质与遗传基因之间的合作伙伴关系——肉体和基因的伙伴关系。

In the spring of 2002, 11 different shell colors lines including 4 orange ,3 purple and 4 white were successfully established by using the mate strategy of self-fertilization.

利用壳色可遗传的特性,采用自体受精的交配策略,于2002年成功地建立了4个橙色、3个紫色、4个白色等3类共11个海湾扇贝自交系,并对不同家系的受精卵大小、胚胎孵化率及幼虫、稚贝和养成阶段的生长速率与存活率等生物学参数进行了比较。

If IQ tests measure a trait that is genetic, and therefore inherited, or a trait that is culturally transmitted by parents and social class, they would, either way, be unlikely to upend the social order in every generation

假如智商测试测量的特性是可遗传的,因而是从先辈那儿继承下来的一个特性,或者是由父母和社会阶级通过文化传播开来的一个特性,那么无论是哪种方式,它们都不可能推翻存在于每一代人中的社会秩序。

Based on the crossing data among these flatfishes, the relationship between pairwise genetic distance and hybrid fitness was evaluated. The findings indicated that positive relationship might exist between genetic distance and hybrid fitness. The pairwise genetic divergence between species decreased as the interspecific hybrid fitness largened. These results implied that speciation clock might exsit in Pleuronectiformes.

根据这几种鲆鲽鱼的杂交是否可行的试验结果,评价种间遗传距离与杂交可适度的关系,结果表明,这8种鲆鲽鱼类的种间遗传距离与杂交可适度呈显著的负相关(r2 = 0.805,P 0.01),即种间遗传分化越大,杂交成功的可能性越小,这表明鲆鲽鱼类中可能存在物种进化的不亲和钟。
