- Barriers to free gene flow between populations are all-important in speciation, the origination of new species. 族群间基因自由流动的障碍,是新物种形成过程中最要紧的关键。
- Scientists in several large research programmes are investigating methods of limiting gene flow in plants. 几个大型研究项目的科学家们正在研究限制植物基因流的方法;
- Gene flow can occur between species, either through hybridization or gene transfer from bacteria or virus to new hosts. 物种之间可能发生基因流动。基因流动既可以通过杂交产生,也可以通过从细菌或病毒至新宿主的基因转移产生。
- These results interpreted that the gene flow, other than drift and inbreeding, plays a critical role in the genetic structure of H, miconioide. 这些结果均表明,基因流是影响七子花种群遗传结构的主要因素,而遗传漂变和近交在其中所起的作用还不明显。
- Gene flow was small and genetic drift and inbreeding might be the main factors influencing population genetic structure of Acer miaotaiense. 庙台槭居群间的基因流很小,遗传漂变和随之而来的近交可能是刻划居群遗传结构的主要因素。
- It is suggested that the gene flow and genetic drift may play an important role in maintaining the level of intrapopulation variation. 我们认为,基因迁移和遗传漂变对?
- There was substantial Gene flow among the breeds as estimated by the structural loci(Nm=7.971) or the microsatellite method(Nm=15.732) . 结构基因座(Nm=7.;971)和微卫星位点(Nm=15
- Implications of local adap tation and some affecting evolutionary factors,such as selection and gene flow,w ere also discussed. 以上效应均结合理论预测和实例分析进行讨论。
- Species can live in the same environment, yet show very limited gene flow due to limited hybridization or hybridization yielding unfit hybrids. 由于有限的杂交或杂交产生不适宜的物种,物种可以生活在同一环境中而只有非常有限的基因流动。
- Adopted gene flow method and applied special breeding scheme software ZUPLAN to analysis the breeding effect of current Merino sheep breeding scheme. 采用基因流动法应用育种规划专用程序ZUPLAN分析研究了细毛羊现行育种方案的育种成效。
- Gene flow among populations is only Nm =0.866, suggesting that gene drift plays an important role in influencing genetic variation and determining genetic structure. 居群间的基因流仅为Nm =0 .;86 6;表明遗传漂变是影响居群遗传变异和遗传结构的一个重要因素。
- The Gst was 0.0673,and the gene flow was 6.9318.There was a strong gene flow among the populations. So the genetic drift would not cause the genetic differentiation. 遗传分化系数(Gst)为0.;0673;基因流(Nm)为6
- Limited gene flow and inbreeding including selfing, outcrossing between sib individuals and clonal reproduction were expected to be responsible for this pattern. 普通野生稻居群遗传变异的这种空间分布式样主要是由于限制的基因流(种子传播)、自交和克隆繁殖所致。
- Maintained gene flow between two populations can also lead to a combination of the two gene pools, reducing the genetic variation between the two groups. 保持两个群体之间的基因流动也可以导致两个基因库的结合,降低了两个群组之间的遗传变异。
- However, besides suitable ecological conditions, the process requires assortative mating to protect the nascent species from homogenization by gene flow. 该谜团是关于新的物种是如何在没有地理屏障区隔群落的情况下发展出来的。
