Although there are many examples of contemporary directional selection, evidence for responses to selection that match predictions are often missing in quantitative genetic studies of wild populations. This is despite the presence of genetic variation and selection pressures - theoretical prerequisites for the response to selection. This conundrum can be explained by statistical issues with accurate parameter estimation, and by biological mechanisms that interfere with the response to selection. These biological mechanisms can accelerate or constrain this response. These mechanisms are generally studied independently but might act simultaneously. We therefore integrated these mechanisms to explore their potential combined effect. This has implications for explaining the apparent evolutionary stasis of wild populations and the conservation of wildlife.
尽管有许多当代定向选择的例子，但在对野生种群进行的定量遗传学研究中，往往缺乏符合选择预测的反应的证据。尽管存在遗传变异和选择压力——这是对选择做出反应的理论前提。这种困境可以用准确参数估计的统计问题以及干扰选择反应的生物学机制来解释。这些生物学机制可以加速或限制这种反应。这些机制通常是独立研究的，但可能同时发生。因此，我们整合了这些机制来探索它们潜在的综合效应。这对解释野生种群的明显进化停滞和野生动物的保护具有重要意义。
