Abstract

Are traits with high levels of plasticity more complex in their genetic architecture, as they can be modulated by numerous different environmental inputs? Many authors have assumed that behavioral traits, in part because they are highly plastic, have an exceptionally complex genetic basis. We quantitatively summarized data from 31 genome-wide association studies (GWAS) and 87 traits in Drosophila melanogaster and found no evidence that behavioral traits have fundamental differences in the number of single-nucleotide polymorphisms or the significance or effect size of those associations, compared with nonbehavioral (morphological or physiological) traits. We suggest the assertion that behavioral traits are inherently more complex on a genetic basis compared with other types of traits should not be assumed true, and merits further investigation.

行为的基因结构是否异常复杂？

具有高度可塑性的特征在遗传结构上是否更加复杂，因为它们可以受到许多不同环境输入的调节？许多学者认为，行为性状具有高度可塑性的部分原因是其遗传基础异常复杂。我们对黑腹果蝇的 31 项基因组关联研究和 87 个性状的数据进行了定量总结，结果发现，与非行为（形态或生理）性状相比，没有证据表明行为性状在单核苷酸多态性的数量或这些关联的意义或效应大小方面存在根本性差异。我们认为，与其他类型的性状相比，行为性状在遗传基础上本质上更为复杂，这种说法不应被认为是正确的，值得进一步研究。

期刊介绍： Current Opinion in Insect Science is a new systematic review journal that aims to provide specialists with a unique and educational platform to keep up–to–date with the expanding volume of information published in the field of Insect Science. As this is such a broad discipline, we have determined themed sections each of which is reviewed once a year. The following 11 areas are covered by Current Opinion in Insect Science. -Ecology -Insect genomics -Global Change Biology -Molecular Physiology (Including Immunity) -Pests and Resistance -Parasites, Parasitoids and Biological Control -Behavioural Ecology -Development and Regulation -Social Insects -Neuroscience -Vectors and Medical and Veterinary Entomology There is also a section that changes every year to reflect hot topics in the field. Section Editors, who are major authorities in their area, are appointed by the Editors of the journal. They divide their section into a number of topics, ensuring that the field is comprehensively covered and that all issues of current importance are emphasized. Section Editors commission articles from leading scientists on each topic that they have selected and the commissioned authors write short review articles in which they present recent developments in their subject, emphasizing the aspects that, in their opinion, are most important. In addition, they provide short annotations to the papers that they consider to be most interesting from all those published in their topic over the previous year.
