您要查找的是不是：
- allopatric introgression 异地渐渗性
- Introgression may take place in such situations. 在这种情况下可能发生渐渗现象。
- Formenkreis A group of related allopatric species or subspecies. 多型种一群相关的异地种或亚种。
- Across geographic gradients, Levins expects allopatric races or coenospecies exist. 穿过地理梯度，莱文斯预料有分布区不重叠的小种或近群种。
- Two or more related species unable to breed because of geographical separation are called allopatric species. 即：一个物种的生物和其他生物之间不能进行杂交。
- The role of introgression in shaping the genetic variation pattern of the species should be seen in the same light. 在形成种的遗传变异型中，种质渗入所引起的作用也应当用同样的见地来看待。
- One of the main trends of lily breeding is to realize introgression between these groups. 实现它们之间的种质渗入是百合育种的主要方向之一 。
- The accessions with introgression from Mesoamerican to the Andean group could be useful as bridge varieties for common bean breeding. 由中美基因库向安第斯基因库渗透的天然杂交种质可为普通菜豆高产、优质、抗逆育种提供有价值的桥梁品种。
- Mayr emphasized the importance of allopatric speciation, where geographically isolated sub-populations diverge so far that reproductive isolation occurs. 迈尔强调异域成种的重要性；在地理上孤立的亚群产生的分歧偏离太远，以致出现生殖隔离。
- When gene introgression requires the spontaneous development of a polyploid, the likelihood of gene introgression is very low. 当基因渗入需要一个自发性多倍体的产生(即杂交种是不可生育的),则基因渗入的可能性变得很小。
- Objectives of our study were to introgress elite subtropical and tropical germplasm with elite U.S.Corn Belt germplasm. 我们的研究目标是将优良的热带和亚热带种质通过渐渗杂交的方式导入美国玉米带种质。
- A methodologies on gene mining, germplasm enhancement and new variety development using the introgression lines and molecular m... 育成了一批高产稳产优质节水抗旱的新品种(系)。
- East Asian forms tend to have more obvious awns than usual, perhaps due to introgression from Alopecurus longearistatus. 这是一根世界的北温带地区的广布的，半水生杂草，到澳大利亚和在别处现在引进栽培。
- In conclusion, the Lanyu pig is a unique breed without gene introgression from exotic pig breeds, but it had sustained loss of heterozygosity. 综合以上之结果，推论保种兰屿猪与以上6个台湾外来猪种间发生基因交流之可能性低为一独特之族群，但此族群可能因近亲配种致其基因多型性流失。
- Over the years, our laboratory has found that Zizania DNA introgression could induce a large number of genetic and epigenetic changes of the rice genome. 我们发现将菰的基因组DNA导入水稻中能诱导水稻基因组发生广泛的基因组变异和表观遗传变异。
- Over the years, our laboratory has found that Zizania DNA introgression could induce a large number of genetic and epigenetic changes in some introgression lines. 我们实验室的前期工作发现将菰的基因组DNA导入水稻中能诱导水稻基因组获得渐渗杂交系发生广泛的基因组变异和表观遗传变异。
- Our results are additional evidence that RAPD variability is not a reliable criterion for taxonomical inference and provide support for allopatric distribution of M. destructor and M. hordei species, in Tunisia. destructor和M.;hordei属于异域分布的观点提供了补充证据。
- For the best use of marker information in a marker aided backcrossing program for gene introgression, a stepwise marker genotyping and individual selection were suggested. 这就是:先根据少数标记对所有个体作初步选择,再根据较多标记对少数个体作精细选择。
- Furthermore, For the introgression of desirable characters from maize relatives into maize, there are considerable genetic and breeding materials were achieved. 此外，还对玉米近缘材料在玉米遗传育种中的应用进行了探讨。
- The result indicated that selection stress was the main reason resulting in the significant deviations of synthetic introgression loci from expected segregation ratios. 人工选择压力可能是导致遗传位点出现偏分离行为的重要原因。
