Sexual Selection: Selfish Genetic Element Encourages Polyandry
نویسنده
چکیده
Selfish genetic elements are ubiquitous and may impact drastically on eukaryote reproduction and evolution. A recent experimental evolution study shows that such elements could also provide an explanation for polyandry.

Does polyandry control population sex ratio via regulation of a selfish gene?
The extent of female multiple mating (polyandry) can strongly impact on the intensity of sexual selection, sexual conflict, and the evolution of cooperation and sociality. More subtly, polyandry may protect populations against intragenomic conflicts that result from the invasion of deleterious selfish genetic elements (SGEs). SGEs commonly impair sperm production, and so are likely to be unsucc...
متن کاملThe polyandry revolution.
The realisation that in the majority of sexually-reproducing organisms from angiosperm to primates females often mate with multiple males (polyandry) is not only revolutionising our understanding of sexual selection, sexual conflict and sex roles, but is also having profound repercussions for a number of other key evolutionary and ecological processes such as the evolution of sociality, sex chr...
متن کاملThe dynamic relationship between polyandry and selfish genetic elements.
Selfish genetic elements (SGEs) are ubiquitous in eukaryotes and bacteria, and make up a large part of the genome. They frequently target sperm to increase their transmission success, but these manipulations are often associated with reduced male fertility. Low fertility of SGE-carrying males is suggested to promote polyandry as a female strategy to bias paternity against male carriers. Support...
متن کاملPolyandry and the Decrease of a Selfish Genetic Element in a Wild House Mouse Population
Despite deleterious effects on individuals, the t haplotype is a selfish genetic element present in many house mouse populations. By distorting the transmission ratio, +/t males transmit the t haplotype to up to 90% of their offspring. However, t/t individuals perish in utero. Theoretical models based on these properties predict a much higher t frequency than observed, leading to the t paradox....
متن کاملDetrimental effects of an autosomal selfish genetic element on sperm competitiveness in house mice.
Female multiple mating (polyandry) is widespread across many animal taxa and indirect genetic benefits are a major evolutionary force favouring polyandry. An incentive for polyandry arises when multiple mating leads to sperm competition that disadvantages sperm from genetically inferior mates. A reduction in genetic quality is associated with costly selfish genetic elements (SGEs), and studies ...
