纯合的

The differentiation coefficient is 0.07 between three inbreed families respectively. The highest level of genetic homozygosity is in families Ⅱ at 18, but genetic variation is a little difference between inbreeding pig and mice. However, this study revealed the pattern of genetic variation at microsatellite loci in the 3 inbred families of WZSP with one of the most important findings to be the high level of unexpected heterozygosity at some loci, e.g. Sw874 and Sw936 that could be part of the unique genetics of three families. A hypothesis is that certain functional genes linked with such microsatellite loci may be involved in the maintenance of viability of these inbred families of WZSP remains for further investigation.

随近交代数的推进，每个星座上等位基因数越来越少，基因的纯合度越来越高，但WZSP近交系微卫星等位基因的纯合度有一定的限度，与近交鼠有所不同；在近交系3个家系各个世代中有少数几个基因座，如Sw874和Sw936等一直处于高度杂合状态，这可能与WZSP近交家系的种质特异性有关，推测与这些基因座处于同一连锁群的某些功能基因在维持极高近交水平下WZSP的基本生存能力中起着关键作用。3个近交群体间的分化系数在0.07以上，已各自成为独立家系；3个家系的近交程度不完全一致，基因的纯合度亦不同，Ⅱ系最高、14个微卫星座中7个纯合，其次为Ⅰ系和Ⅲ系。

The leafstalk, chief vein, bud, the cane top on side branch, bast and xylem of type B had type A and C tow components, belonging to chimeric tissues. The leaf pulp and thin leaf vein had no components of type C, belonging to pure tissues of type A. Type B plant had two kinds of color roots, the rufous roots belonged to type A tissue, the yellow roots belonged to type C tissue through the SSR identification.

深州杨B型的叶柄、叶主脉、芽、侧枝茎尖、韧皮部、木质部同时检测到深州杨A、C型两种成分存在，属于嵌合组织，B型叶肉及细叶脉中检测不到深州杨C型成分，属于深州杨A型纯合组织；深州杨B型植株的地下部分含有红褐色和土黄色两种根，经检测，红褐色根是属于深州杨A型的纯合组织，土黄色根是属于深州杨C型的纯合组织。

In order to enhance its resistance to bacterial blightand lepidopteran such as leaffolder, striped stem borer and yellow stem borer etc, we intergessed Xa21 and Bt genes into the genetic background of 93-11 by backcross scheme, combining with molecular marker-assisted selection and phenotypic selection. Through three backcross and two self generations, eight families that have homozygous Xa21 and Bt genes were obtained in the BC3F3 families. Two families show higher recovery percentage of 93-11 even up to 90.59%.

为了进一步提高其对白叶枯病的抗性、同时增加其对水稻鳞翅目害虫（如稻纵卷叶螟、二化螟和三化螟等）抗性，利用常规回交育种方法和结合分子标记辅助选择将Xa21基因和Bt基因同时导入93-11中，在BC3F3家系中筛选到8个家系含纯合的Xa21基因和Bt基因，其中有两个家系与93-11比较其遗传背景的回复率很高，达到90.59%。

The study indicated that sufficient numbers of wheat/rye translocations can be produc ed for wheat breeding with crossing octoploid triticale and common wheat.

小麦-黑麦染色体易位主要发生在杂种的早期世代，使用适当的选择技术在F3获得了纯合的易位植株。

Homozygous tetraploid is a relatively balanced system,the continued selection is invalid.

纯合的四倍体是一个相对平衡的系统，继续选择是无效的。

The embryonic analysis results indicated that the disruption of oxt gene would lead to the disruption of wg transcription and the expression of engrailed gene, as the wg transcription is dependant on the Engrailed.

进一步结合运用FLP-FRT系统，用缺损GFP蛋白的表达来标记纯合的oxt突变基因克隆，针对眼睛成虫盘的克隆分析结果表明，在oxt突变克隆中，Hh下游的Ci蛋白的表达区域完全消失。

Selection of the silkworm varieties that ingest artificial diets and analysis of feeding habit heredityIn order to obtain a pure line omnivorous system of silkworm variety which is suitable for artificial diet, two varieties, Selected 01 and Selected 02, were chosen for further selection in continuous generations. The average feeding ratio on mulberry free artificial diet of newly hatched larve reached 99.0% after the selection.

人工饲料摄食性优良品种选拔及遗传分析为获得纯合的对不含桑叶粉人工饲料食性优良的广食性系统，对筛选出的摄食率较高的两个品种选01和选02进行累代选择，蚁蚕对不含桑叶粉人工饲料的平均摄食率分别达到99.0%以上。

The two ways that load -bearing walls are made are masonry walls and veneered walls.

多数植物带有大量有害的隐性基因的&遗传负荷&，其中少数是纯合的，因而降低了生长。

Ten leaves per 2 replicates were collected in each sampling on natural, pure and mixed hedgerows.

取样应包含自然的，纯合的，和混合的三种灌木树篱。

Sixty per cent of the studied pollen plants were diploids,and set seeds normally.

结果观察到60％的花粉植株为能正常结实的二倍体。90％来自F_1的花粉植株的后代是整齐一致没有分离的，也即在遗传上是纯合的。

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