Asymmetric over-introgression of the indica alleles on chromosome 7 and many specific regions on other chromosomes in the japonica genetic background is consistent with the general trend observed in the RIL and F_2 populations of the same cross, suggesting a high genetic load in the japonica gene pool, and japonica genome experienced a very severe bottleneck by artificial domestication.2 Genetic background effect on QTL expression of grain weight and its related traitsGenetic background effect on main-effect QTL and digenic epistatic QTL mapping for GWT and its related traits including GL, GW and GT was dissected by a large set of reciprocal introgression lines and recombinant inbred lines derived from Lemont and Teqing in Beijing environment.

籼粳相互导入具有不对称性，粳稻向籼稻背景的平均导入频率与期望值相仿，相反籼稻向粳稻背景的平均导入频率大大高于理论预期，位于第7染色体和一些其它染色体的特殊区段存在籼稻等位基因的超导入现象，在来自相同亲本的重组自交系和F_2群体中也观察到同样的导入趋势，表明粳稻基因组具有较大的遗传负荷，粳稻品种在人工驯化过程中曾经历过一个非常剧烈的遗传瓶颈。2水稻籽粒相关性状的主效和互作QTL表达的遗传背景效应利用Lemont和特青培育的双向导入系和重组自交系群体，在北京环境下定位影响千粒重及其相关性状如粒长、粒宽和粒厚的主效和互作QTL，分别在特青背景导入系、Lemont背景导入系和重组自交系下检测到影响千粒重及其相关性状的主效QTL分别为33个、27个和13个，互作QTL分别为4个、8个和23个，其中仅有6个主效QTL(QGwt5，QGl1，QGl3b，QGl4，QGw7和QGw8)在籼粳两个不同背景下共同表达，3个主效QTL(QGwt5，QGwt7a和QGt5)在导入系和重组自交系中共同表达，分别占检测到影响这些性状QTL总数的11.1%和4.3%，未检测到在3个背景下相同表达的互作QTL。

The plum-apricot germplasm resources were analyzed by RAPD markers. The results showed that plum-apricot was more close to the related species with low polymorphism. The clustering results were indicated that most plum-apricots were more close to Chinese plum with the similarity of morphological description, thus the female parent for plum-apricot was probably plum in the occurrence naturally. The result of S allele-specific PCR amplification showed that plum-apricot had only one band with the similarity with plum, thus evolution similarity of plum-apricot was more close to plum than apricot.

5对参试杏梅种质资源的RAPD分析表明，杏梅与其近缘种之间亲缘关系较近，多态性相对较少；聚类分析结果显示大部分的杏梅与中国李的遗传距离较近，与形态学上的描述基本一致，因此杏梅种质资源在自然界中产生时，其母本可能为李；同时S等位基因的扩增结果显示杏梅与李的扩增条数一致，都为一条，因此推断杏梅与李的进化趋同性可能较杏更近。

Imagine, for example that there is one gene in parasites with two alleles p and P conferring two types of parasitic ability, and one gene in hosts with two alleles h and H, conferring two types of parasite resistance, such that parasites with allele p can attach themselves to hosts with the allele h, and P to H.

例如，想象一下，寄生虫的一个基因有两个等位基因p和P赋予两种类型的寄生能力，而寄主的一个基因有两个等位基因h和H赋予两类对寄生虫的抗性。带等位基因p的寄生虫可以将它们自已附在带等位基因h的寄主上，而带等位基因P的寄生虫可以将它们自已附在带等位基因H的寄主上。
