变异发生

The functional allele at the W locus is Ipmyb2, which was newly found in Chinese populations, and it differs mainly in the intron regions from those of the reported allele Ipmyb1; in comparison to Ipmyb2, the newly found second allele ipmyb2 has eight substitutions in the exons, a 6-bp deletion, and a 19-bp deletion, causing ORF shifting, and exists mostly in white-flowered individuals.

以上结果表明：1花青素代谢途径上酶基因的位点均有一定程度的多态，其中尤以ANS为最高；调控基因ipmyb2的核苷酸缺失造成该基因停止功能，使其纯合子的个体开白色花。2授粉者所介导的花色表型选择确实在中国种群中发生，有可能进一步增加花色代谢途径上基因位点的遗传变异。

These deficiencies result from the facts(1)that the subjectivity of policyimplementers can vary policy information in constructive and distorting cognition;(2)that policyimplementing subjects are not well-learned;and(3)that the referents of linguistic symbols withpolicy information are not definite.

产生这些认知缺陷的原因主要在于：1、政策认知的主体性特征会通过建构性认知和扭曲性认知致使政策信息在认知过程中发生变异；2、政策执行主体的知识素质偏低；3、承载政策信息的语言符号指代关系具有不确定性。

Results: YMDD mutation were not detected in the serum before Lamivudine therapy of the 40 patients with HBV DNA relapse.

结果：40例发生血清HBVDNA反跳的HBeAg阳性CHB病人，拉米夫定治疗前的血清中均未检出YMDD变异株。

One such example is the sound shift that gradually occurred in the Germanic languages in the first millennium B.C.

这类变异的一个例子是在公元前第一个1000年日耳曼各种语言逐渐发生的语音演变。

Variable decelerations are characterized by the variable onset of abrupt slowing of the FHR in association with uterine contractions.

变异减速的特点是与宫缩关系不是恒定的突然发生的胎心率减慢。

Variable decelerations are characterized by the variable onsetof abrupt slowing of the FHR in association with uterinecontractions.

变异减速的特点是与宫缩关系不是恒定的突然发生的胎心率减慢。

The number of mutations over time helped the team estimate when the duplications in soybeans took place.

长时间内变异的次数将会协助科学家们估测出大豆复制发生的时间。

There must be some efficient cause for each slight individual difference, as well as for more strongly marked variations which occasionally arise.

每一微小的个体差异，以及偶然发生的较显著的变异，都有其充分原因。

Senior author Duska Dragun, MD, from the Department of Nephrology and Intensive Care Medicine, Charite University Hospital–Campus Virchow Clinic, Berlin, Germany, and colleagues in Berlin and in Melbourne, Australia, investigated whether the COMT variant with lower activity predisposes patients to acute kidney injury and prolonged vasodilatory shock after bypass surgery because of the increase in plasma catecholamines.

资深作者、来自德国柏林Charite大学医院校园Virchow诊所肾脏科的Duska Dragun医师与澳洲墨尔本及柏林的同事们研究COMT基因变异是否会降低病患接受绕道手术后，因为血中儿茶酚胺浓度上升，发生急性肾脏损伤与血管扩张性休克的机率。

Dr. Stefansson said it was conceivable that in people with the double variants the thyroid cells were not properly differentiated, and that the immature cells might be the cause of cancer.

Stefansson博士说，不难想象有这2个遗传变异的人，甲状腺细胞不能正常分化成熟，那些不成熟的细胞可能是甲状腺癌发生的原因。

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。
