The genetic architecture of colour polymorphism and speciation

点击翻译按钮获取中文摘要

Speciation, the process by which populations diverge and become distinct, is the engine that drives biodiversity and Darwin's 'mystery of mysteries'. Speciation is accelerated in species with multiple, discrete, coexisting colour forms; yet the genetic mechanisms underpinning this pattern are not known. This project aims to identify the genes underlying different colour forms and how they are distributed across the genome. The project plans to test the prediction that these same areas of the genome show marked divergence between lineages that are in the process of becoming distinct species. Doing so may contribute significantly to our understanding of speciation, underlying genetic mechanisms, and genes generating colour variation in vertebrates.
