遗传因子的

Second, differences in some characteristics between wild and mass-reared melon fly strains in Okinawa are reviewed, and the genetic factors which can cause these differences are discussed.

二综论琉球野生及大量饲育之瓜实蝇在某些特性上之差异，并讨论造成这些差异的遗传因子。

Thus, phenotypically similar conditions may be due to mutations in different genes, nongenetic factors, or both.

因此表型相似可因不同基因的突变和/或非遗传因子所造成。

Thus, phenotypically similar conditio may be due to mutatio in different genes, nongenetic factors, or both.

因此表型相似可因不同基因的突变和/或非遗传因子所造成。

In view of disadvantages in present defect reconstruction methods,such as over-long time or excessive need for training samples,a new defect reconstruction method based on similar model and genetic algorithm was investigated as follows:similar model between non-axisymetric defect and axisymetric defect was represented,and proportionality factor was deduced by skin depth equation.

针对以往缺陷重构方法中普遍存在的计算时间长或需要大量训练样本的缺点，提出一种基于相似模型和遗传算法的缺陷快速重构方法，分析非轴对称缺陷与轴对称缺陷之间存在的相似模型，并利用集肤深度公式推导出两者之间的缩比因子，从而将耗时巨大的缺陷重构问题转换为二维轴对称情况下的计算问题；同时为进一步缩短重构时间，提出一种加快遗传算法收敛速度的方法。

This paper investigats the genetic diversity of the wolf spider (Pardosa pseudoannulata BSenberget et strand 1906) by using the SRAP reaction system and analyzes the effect which ecological factor carried on genetic diversity.

利用SRAP标记对不同地理区域的拟环纹豹蛛(Pardosa pseudoannulata BSenberg et strand 1906)种群遗传多样性进行研究，分析了不同生态因子对拟环纹豹蛛种群遗传多样性的影响。

Presence of a genetic factor like azoospermia factor microdeletions may lead to irreversible spermatogenic arrest in these cases.

遗传因子如无精子因子微缺失的存在可能在这些病例中导致不可逆的精子发生阻滞。

Segregation Distorter is a meiotic drive system of natural occurrence. Heterozygous SD／SD＋ males transmit the SD chromosome in vast excess over the normal homolog.

黑腹果蝇中的分离变相因子［Segregation Distorter］是一种非常典型的具有减数分裂驱动性质的特殊遗传因子。

Transposable elements are important factors to cause genetic variation and recombination, which are widely spreaded in eukaryotic organisms.

转座元件是一类广泛分布于真核生物的可移动的遗传因子，可以引起基因重组和变异，在物种进化及遗传改良中起着重要作用。

Begg argues that all risk factors for breast cancer are overrepresented in incident cases of breast cancer, so that a sample of women who have been diagnosed with breast cancer and who are identified as mutation carriers are more likely to have other breast cancer risk factors than similar mutation carriers who are disease-free.

Dr。 Begg认为，所有的乳腺癌危险因子在乳腺癌病例中都被高估，所以一些已经被诊断为乳腺癌，且确认是某种基因突变的携带者妇女，比起具有相似的遗传突变的健康携带者，更可能是其他乳腺癌的危险因子导致疾病发生。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
