Dr Gaulin thinks an evolutionary fight is going on between natural selection, which conserves metabolic expenditure and promotes longevity, and sexual selection, which willingly trades both for extra mating opportunities.

Gaulin博士认为自然选择的目标和性选择的目标在进化中互相冲突，自然选择倾向于保存自己，降低代谢强度，让自己活得更长；而性选择的目标是为了得到更多的交配机会，不惜以代谢强度和长寿为代价。

Because muscles come at such cost, Dr Gaulin thinks an evolutionary fight is going on between natural selection, which conserves metabolic expenditure and promotes longevity, and sexual selection, which willingly trades both for extra mating opportunities.

肌肉的存在要付出相当代价， Gaulin博士认为自然选择的目标和性选择的目标在进化中互相冲突，自然选择倾向于保存自己，降低代谢强度，让自己活得更长；而性选择的目标是为了得到更多的交配机会，不惜以代谢强度和长寿为代价。

In a large, randomly mating population that is free of disturbing forces, allele and genotypic frequencies do not change and are related in a simple way.

在一个大的，随机交配的人口是免费的令人不安的力量，等位基因与基因型频率不改变，并在有关的一个简单的方法。

Second, a lot of artificial propagation experiments were performed between different gynogenetic clones to analyze whether or not genetic recombination occurs by utilizing the identified RAPD and SCAR markers. Direct molecular genetic evidence for gonochoristic reproduction was revealed in the gynogenetic silver crucian carp, and a previous hypothesis that the silver crucian carp might reproduce both gynogenetically and gonochoristically was conformed.

二是利用银鲫的克隆多样性和其种群中存在的雄性个体，设计大量的不同繁育组合，运用已鉴定的RAPD和SCAR分子标记，分析比较了不同繁育组合子代的DNA扩增情况，探讨了这些分子标记在各个交配子代中的重组分布规律。

In this study, the genetic structure and genetic diversity of cultured and wild Pacific abalone Haliotis discus hannai were analyzed using AFLP technique on the basis of investigation of the inheritance mode of AFLP markers, and genetic linkage maps of female and male H.

本文通过分析皱纹盘鲍AFLP分子标记的遗传模式，利用AFLP技术对皱纹盘鲍养殖与野生群体进行了遗传多样性及遗传分化研究，并对皱纹盘鲍单对交配的亲本及其F1子代进行AFLP和微卫星作图标记筛选，建立了初步的遗传连锁图谱。

In Ecuador, there are also white or yellow Heliconius butterflies that live close to one another and have mated freely.
