In our study, HaPLE2 was observed in all individuals within the three populations,but HaPLE1 was not. Generally,inactive copies of a transposable element will be fixed or lost in the genome of individuals in a population over time if they are neutral.

因为当一个转座子失去活性时就被固定在基因组上,这个基因也会由于遗传而出现在下一代的基因组中,当在室內连续饲养几代之后,这个基因就会存在于几乎所有的个体中,而HaPLE1只存在于24-35%的棉铃虫个体的基因组中。5 piggyBac转座子基因的亲缘关系树分析收集各种数据库登录的来自11种生物的19个piggyBac类似因子的氨基酸序列,利用CLUSTALX1.8和MEGA3.1构建亲缘关系树,进行系统进化分析。

In additional, there are forum that is set up to provide a place of communication.This website contain several parts, that is biology pandect, the origin of life, biology research, the material of life, enginery of biology, individual development, the development of colony, the world of biology.

该站涵盖了生物总论、生命起源、生物学研究、生命物质、生物机能、个体发展、群体发展以及生物世界等多个部分,涉及了史前生物、植物、动物、昆虫、微生物领域。

The relationship between education and human evolution is also studied. Education is playing a very important role both in the human development as a whole and an individual, it points out that human biological growth and education are interactive which leads to the exposition of educational biological function on which the well-born bioengineering and well-bred educational engineering are presented.

研究了教育与人的生物发展,从人类整体生物进化与个体相应发展上探讨了教育的作用,指出人的生物发展对教育的制约性和教育对人的生物发展的巨大作用,从而阐明了教育的生物功能并据此提出优生的生物工程学和优育的教育工程学,这也颇具新意。

Fisher took what appeared to be a community of flittering butterflies evolving over time and saw them as a whole system transmitting differentiated information in parallel through a population.

费希尔在1929年写的《自然选择的遗传理论》(The Genetical Theory of Natural Selection,顿时受到启发。是达尔文带头把研究个体生物相应地转变为研究由个体生物组成的群体,而把种群想法转变为定量科学的是费希尔

从结果 如表2,很难找到一个简单的相关性生物个体之间的浓度胺和啤酒的类型。

The results showed that there existed significant difference in RAPD between different biotypes as well as among individual BPHs, and genetic purifying could lessen this difference in the level of individuals but not in the level of biotypes.

结果发现:家系纯化对褐飞虱个体及生物型1和生物型2群体的致害力均有影响,个体间存在的致害力差异有所减小,但未能消除;两种生物型群体的致害力均显著下降,至第五代时对感虫对照TN1的致害力已分别下降了23%和16%,然而各自的致害特征并未发生根本性的变化,表明它们的致害特性是相对稳定的。
