Abstract

Supergenes, or regions of the genome containing two or more linked functional mutations that control complex traits, are emerging as a common genetic basis for many striking phenotypic polymorphisms in insects. Now that we know that supergenes are common, we can seek common features of diverse supergene systems. Here, we lay out a framework of open questions (see graphical abstract) that can be addressed separately in each system and, ultimately, compared across systems to seek general patterns in supergene evolution. Few empirical studies have investigated what causes new supergene haplotypes to initially increase in frequency, but to not eventually fix in a population. Resolving the genotype-phenotype connection and isolating functional genes will provide more insight into the forms of selecting shaping supergene evolution. Ultimately, research on supergenes will help to broaden our understanding of how recombination rate variation influences the evolutionary trajectories of sexually reproducing organisms.

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.
