查询词典 gene flow

However, it remains unclear how reliable cleistogamy is for gene flow mitigation: a Co-Extra research project on rapeseed investigating the matter has published preliminary results which cast doubt on the attainment of a high degree of reliability.

然而，目前还不清楚闭花受精对缓解基因流有多可靠。Co-Extra项目以油菜籽为材料研究了这个问题，已经发表了初步结果；这些结果使他们对能否高度可靠地缓解基因流产生了怀疑。

The approaches for decreasing the gene flow include chloroplast transformation, pollen sterility, seed sterility, cleistogamy, apomixis, temporal control, and transgenic mitigation.

目前降低外源基因扩散的方法主要有叶绿体转化、花粉不育、种子不育、闭花受精、无融合生殖、暂时性控制及转基因缓和等。

The analysis of molecular variance revealed that 93.85% of the variance component was attributable to the variation among individuals within ditches. Low levels of the genetic differentiation coefficient among ditches, G=0.172 and Nm=2.4, indicated that the ditches barely hinder gene flow between Scaevola populations. UPGMA cluster analysis and principal coordinate analysis revealed no major groupings among ditches or among plants.

经过分子变方分析显示海南草海桐有93.85％的变方成分存在於个体间；POPGENE分析结果显示其遗传分化系数G(下标 ST为0.172，而基因流为2.4，显示沟渠并无阻碍基因交流之能力；UPGMA归群分析及主座标分析结果显示海南草海桐个体间几乎无差别或差异很小。

Gene flow describes he movement of genes among populations through interbreeding, dispersal and migration.

基因流描述的是基因在种群内通过相互杂交，扩散和迁移进行的运动。

Some degree of gene flow may be a normal, evolutionarily constructive process, and all constellations of genes and genotypes cannot be preserved however, hybridization with or without introgression may, nevertheless, threaten a rare species' existence.

某种程度的基因流动是正常的、积极的进化过程；不可能所有基因和基因型的排列格局都被保存；但是，有或无基因渗入的杂交会威胁珍稀物种的生存。

10The simulations of an empirical model indicated that, when the outcrossing rate was no more than 1%, a 2 m buffer area with pollen receiver individuals between pollen donor and receiver was sufficient to minimize the frequencies of gene flow to .9%.

对栽培稻到其野生近缘种的基因漂移进行模拟的结果表明，栽培稻到野生稻的基因漂移频率较高并且可能会对邻近的较大范围内的野生近缘种群体造成影响。

The model simulations indicated that, when the outcrossing rate was no more than 1%, a 5 m buffer area with pollen receiver individuals between pollen donors and receivers was sufficient to minimize the frequencies of gene flow to .9%.

然而，对栽培水稻到其野生近缘种的基因漂移进行模拟的结果表明，栽培水稻到野生稻的基因漂移频率较高并且可能会对邻近的较大范围内的野生近缘种群体造成影响。

This pattern of genetic structure implies non-random mating and restricted gene flow among eels from different sampled locations, which therefore refute the hypothesis of panmixia.

这种遗传结构暗示非随机交配模式和不同区域样品间存在一定限制的基因流，因此否认了随机交配假说。

More and more studies have been carried out on population genetic structure of rotifer population and gene flow by molecular technologies to assess the effect of cyclic parthenogenesis and resting egg bank on rotifer's genetics and evolution.

由于循环孤雌生殖和休眠卵库的存在，使得轮虫种群内的遗传变异和种群间基因流模式有别于其他动物。目前，国外有关轮虫分子遗传和进化的研究还刚刚起步，国内还没有这方面的报道。

Genetic diversity analysis within and between the green peafowl and the blue peafowl populations demonstrated that the expected heterozygosity of two peafowl populations were 0.2482 and 0.2744, respectively. The inbreeding index, Reynolds' genetic distance and gene flow between the two populations were 0.078, 0.0603 and 3.896 respectively. These results indicate that the heterozygosity and the genetic diversity of these two peafowl populations were very low, and suggest a tendency towards intermixing.

蓝孔雀和绿孔雀群体间和群体内的遗传分析结果表明，绿孔雀和蓝孔雀两个群体的期望杂合度分别为0.7422和0.6943，群体间的遗传分化系数为0.078， Reynolds'遗传距离和基因流分别为0.0603和3.896，结果显示这两个孔雀群体的杂合度和遗传多样性水平都很低，且有相互混杂的趋势。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
