查询词典 introgression

Gene introgression is usually resulted from spontaneous hybridization occurring among closely related species in sympatric populations and thus has great impact on genetic structure of natural populations.

同域分布的近缘物种常常发生杂交而导致种间基因渐渗，从而对相关物种的自然居群遗传结构产生重要影响，近缘种间的杂交渐渗已成为进化生物学和保护生物学关注的热点。

Lysine content, kernel phenotype, zein accumulation and opaque-2 gene sequence of four maize inbred lines (CA335, CA339, Lu2548 and Qi205) were investigated in this study. These QPM inbred lines as the donor of Opaque-2 mutant gene (o2) respectively, were backcrossed to introgression o2 into elite maize inbred lines based on marker-assisted.

对CA335、CA339、山东2548和齐205等4个国内常用优质蛋白玉米自交系的赖氨酸含量、籽粒表型、醇溶蛋白积累及opaque-2基因的序列进行了分析；对不同自交系作为Opaque-2突变基因（o2）基因供体的分子标记选择效果进行了初步的比较。

Was used as the recurrent parent and 7 varieties of diverse origins (6 are indica lines) were used as donors to obtain BC2F2 bulks by crossing and continued backcrossing. Initial screening for CT under the low temperature of the field conditions resulted in 177 CT BC2F2 introgression lines.

结果表明，虽然供体亲本均为苗期耐冷性弱的品种，但在全部回交后代中均出现耐冷性的超亲分离，表明这些供体亲本均携带对耐冷性有利的&隐蔽基因&，但组合间的耐冷性选择效率存在较大差异。

In this study, we use both morphological and molecular (mtDNA Cyt-b) methods to identify the exotic sturgeons in Taiwan and both the phylogeny and the genetic introgression of the fish were analyzed meanwhile.

本研究以分子遗传学方法(mtDNA Cyt-b)辅以形态学方法鉴别台湾引进的鲟种类，并探讨鲟的类缘关系以及因杂交而造成的基因渗入现像。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
