Since 1996, the Rice Research Institute of Liaoning Province has laid stress on the genetic improvement of stigma exsertion rate of japonica male sterile lines. By introducing the genes of high stigma exsertion rate from indica into japonica, a group of japonica male sterile lines with high stigma exsertion rate have been successfully developed. Their stigma exsertion rate have been greatly increased from less than 30% to more than 80%, resulting in an increased outcrossing rate over 60% and a high seed production yield of 3.0~4.5 t/hm^2. Moreover, using these sterile lines, a group of new japonica hybrid rice combinations such as Liaoyou 5218 (Liao 5216A/C418), Liaoyou 1052 (Liao 105A/C52) have been developed and released to commercial production.

自1996年以来，辽宁省稻作研究所加强了粳稻不育系的柱头外露率遗传改良研究，通过导入籼稻的高柱头外露率基因，选育了一批高柱头外露率的粳型不育系，柱头外露率由原来的30%以下逐步提高到80%以上，异交结实率可达到60%以上，杂交制种产量可提高到3.0~4.5t/hm^2，并配组育成了辽优5218（辽5216A/C418）、辽优1052（辽105A/C52）等杂交粳稻新组合，在生产上得到了大面积推广应用。

If you'd like to know your lifetime risk of type 2 diabetes or whence your forbears came, there's probably a Web-based genetic testing company out there that can tell you.

如果你想知道你生命中2型糖尿病的风险或者是你的祖先的根源来自于哪里，会有一个网上的遗传检验公司能够告诉你。

Mutation rate at exon of GH in five bovine species was very low with the percentage of 3.48%. The majority of nucleotide substitution was nonsense mutation and only one missense mutation was observed. Molecule tree based on haplotypes of bGH at exon 5 showed that differentiation was apparent relatively between Bubalus bubalis and Bos taurus, Bos indicus, Bos grunniens, Bos frontalis. There was no apparent differentiation among other four bovine species and they shared mutual ancestral sequence.

序列分析表明，5个牛种GH基因外显子5的遗传变异水平较低，平均核苷酸变异率约为3.48%，而且绝大多数位点的核苷酸替换是同义突变，仅发现1个错义突变位点；从GH基因外显子5序列单倍型构建的分子进化树来看，水牛与普通牛、瘤牛、牦牛及大额牛的分化相对比较明显，其他4个牛种之间并无明显分化，还享有共同的祖先序列。

This paper reviewed the advances in honeybee breeding involving to estimate the numbers of subfamilies in a colony and analyze the genetic correlation among workers; guess the polyandry level of queens and identify the purity of a subspecies; build a linkage map and discriminate loci of quantitative traits; genotype and distinguish full sister from semi sisters; analyze the trend of sperm to inseminate an egg and so on by means of such molecular biotech as microsatellites DNA, mitochondria...

What we're finding in insects is that they become obese when parasites cause inflammation that affects metabolism," said Marden."That seems akin to what's happening in humans when they get type-2 diabetes. It's not because there's been a change in the genetic composition of the population. it's because something has changed in our enironment.

我们发现的是当昆虫体内的寄生虫触发可以影响代谢的炎症反应时，昆虫发胖了" Marden说，"患有2型糖尿病的人似乎与这种发现相似，并不是人群中的遗传组成发生了改变，而是体内环境发生了改变。

Then based on the least squares support vector machine method, the modificatory model of the main environmental factors effect on the tanδ was advanced, and the genetic algorithm method was used to optimize the parameters of this model.

根据人工气候室内变压器套管tand的在线测量试验结果，分析了环境因素对电容型设备tand的影响情况，提出了基于最小二乘支持向量机的主要环境因素对tand影响的修正模型，并采用遗传算法优化了支持向量机的参数。

The nitrate non-utilizing mutantas an another added genetic marker was used to select the out-crossed perithecium from self-crossed perithecia. Seven crosses were tested in all, including cross between S×S, MR ×S, MR×MR,HR ×S, as well as HR ×MR. The results showed that no recombinant phenotype was found among all progeny of seven crosses. Progeny segregation of crosses between the parents with different sensitive levels (i.e. MR×S, HR×S,HR×MR) clearly fit a 1:1 ratio of two parental phenotypes, and no segregation was found in the crosses of S×S and MR × MR.

从25个敏感菌株和31个抗性菌株中随机挑选了2个S、3个MR和1个HR，并以硝酸盐营养缺陷型突变体作为另一个遗传标记，按照S×S、MR×MR、MR×S、HR×S、HR×MR等共设计了7个杂交组合，对各杂交后代对多菌灵的敏感性测试发现，在所有杂交后代中均未出现除双亲表现型以外的重组型个体，MR×S、HR×S及HR×MR的杂交后代出现了1∶1的分离比例。

Given this assumption, even if the parameters of the system are randomly perturbed, by either genetic mutation, environmental variance or experimental manipulation during development, the system will generate a limited and discrete subset of phenotypes.

而在这种假设的前提下，即使系统各参数值在发育过程中受到随机的扰动（或者是遗传突变，或者是环境变化或人工实验操纵），系统也会产生出某个有限的、离散的表型[11]子集。
