The Role of Fluctuating Asymmetry in Mate Choice

9521821摩尔，我们的研究询问女性是否根据男性在发育过程中承受压力的能力而区别对待男性。这种能力反映在具有双边表达的人物的波动不对称程度上。我们将结合实验操作、遗传实验和对蟑螂Nauphy eta Cinera的相关性研究来解决几个问题：1)雌性选择配偶或雄性竞争是否受到不对称程度的影响；2)减少不对称的能力是由基因决定的；以及3)环境和近亲交配程度是否影响波动不对称的重要性？这项研究将提供有助于将在生物防治和濒危物种计划中饲养的个体的交配劣势降至最低的信息。这些计划依赖于建立目标物种的繁育种群。要想成功，我们必须知道受控繁殖计划的个体在自然栖息地的交配竞争中表现如何。在这些项目中，许多用来饲养昆虫以供释放的做法，如近亲繁殖，导致波动不对称增加。我们的研究将提供关于不对称程度的女性歧视如何影响交配模式的信息。

9521821 MOORE Our research asks whether females discriminate among males on the basis of the male's ability to withstand stresses during development. This ability is reflected in the degree of fluctuating asymmetry in characters that have bilateral expression. We will use a combination of experimental manipulations, genetic experiments, and correlation studies of the cockroach, Nauphoeta cinera, to address several issues: 1) is female choice of mates or male-male competition influenced by the degree of asymmetry; 2) is the ability to reduce asymmetry genetically determined; and 3) do environment and degree of inbreeding influence the importance of fluctuating asymmetry? This research will provide information that will help minimize the mating disadvantages of individuals reared in biological control and endangered species programs. These programs rely on establishing breeding populations of target species. To be successful we must know how individuals from controlled breeding programs fare in competition for mates in a natural habitat. Many of the practices use to rear insects for release in these programs, such as inbreeding, result in increased fluctuating asymmetry. Our research will provide information on how mating patterns are affected by female discrimination against the degree of asymmetry.
