Individual animals usually exhibit flexibility in their behaviour, but some behaviours are genetically determined. An extreme example of genetically fixed alternative behaviours occurs in a wading bird, the ruff. The ruff has a "lek" mating system in which males invest all their energy into attracting females to mate with them, and none into parental care. Territorial breeding males have spectacular plumes around their neck and head, and vary enormously in colouration, so that each male at the lek is distinguishable. Other nonterritorial "satellite" males, which are distinguishable by their white feathers, concentrate on "stealing" matings from territorial displaying males. Whether a male becomes a territorial or satellite individual is genetically determined. Satellites are essentially parasitic on territorials, though there is evidence that territorials may benefit from the presence of a small number of satellites. A third type of male, which mimics females, was recently discovered. This parasitic male is able to "hide" from the other males at the lek, so avoiding territorial aggression, and also succeeds by stealing matings from the resident males. The purpose of this study is to use genome sequencing to identify the genes that make the males behave in these three different ways. We want to understand how the three different strategies can coexist in the population, and how they have evolved. We also plan to discover the genetic mechanism to explain why males are so diverse in their plumage. These mechanisms are likely to be the same ones that produce some of the similar variation that we normally only see between species. Finally, we want to discover the mechanism that ensures that the plumage pattern and behaviour are co-inherited.

个体动物通常表现出灵活的行为，但有些行为是由基因决定的。一个极端的例子，基因固定的替代行为发生在涉禽，皱领。皱领有一个“列克”交配系统，雄性把所有的精力都花在吸引雌性与他们交配上，而没有花在父母的照顾上。领地繁殖的雄性在脖子和头上有壮观的羽毛，颜色变化很大，所以每只雄性在列克都是可以区分的。其他非领土“卫星”男性，这是由他们的白色羽毛区分，集中在“窃取”交配从领土显示男性。一个男性是成为领地个体还是卫星个体是由基因决定的。卫星基本上是寄生在领地上的，尽管有证据表明领地可能会从少量卫星的存在中受益。最近发现了第三种模仿雌性的雄性。这种寄生的雄性能够“隐藏”在列克的其他雄性，从而避免领土侵略，并成功地从居民雄性那里窃取交配。这项研究的目的是利用基因组测序来确定使雄性以这三种不同方式行为的基因。我们想了解这三种不同的策略是如何在种群中共存的，以及它们是如何进化的。我们还计划发现遗传机制来解释为什么雄性的羽毛如此多样化。这些机制很可能是产生我们通常只在物种之间看到的一些类似变异的机制。最后，我们希望发现确保羽毛模式和行为共同继承的机制。
