遗传冗余的进化:基因型-表型作图中复杂性的相关性

Evolution of Genetic Redundancy : The Relevance of Complexity in Genotype-Phenotype Mapping

Nen Saito, Shuji Ishihara, Kunihiko Kaneko

摘要:

遗传冗余是普遍存在的,可以在任何生物体中找到。然而,有人认为,遗传冗余会降低总的种群适应度,因此,冗余不太可能进化。在这封信中,我们研究了一个进化模型与高维基因型-表型映射(GPM)调查的相关性的复杂性GPM的遗传冗余的进化。通过应用复制方法处理淬灭随机性,解析地得到了适应度的冗余依赖关系,证明了在GPM较复杂的情况下,遗传冗余确实是可以进化的.我们的研究结果提供了一个新的见解如何遗传冗余进化。

英文摘要:

Genetic redundancy is ubiquitous and can be found in any organism. However, it has been argued that genetic redundancy reduces total population fitness, and therefore, redundancy is unlikely to evolve. In this letter, we study an evolutionary model with high-dimensional genotype-phenotype mapping (GPM) to investigate the relevance of complexity in GPM to the evolution of genetic redundancy. By applying the replica method to deal with quenched randomness, the redundancy dependence of the fitness is analytically obtained, which demonstrates that genetic redundancy can indeed evolve, provided that the GPM is complex. Our result provides a novel insight into how genetic redundancy evolves.
