检测和理解自然群体中上位性的能力对于理解遗传变异如何影响生物性状非常重要。然而,由于多重比较产生的统计问题以及大多数遗传变异以低等位基因频率分离的事实,自然群体中上位性的识别和表征仍然很困难。在这篇综述中,我们讨论了如何使用模型生物体来操纵基因型组合,以支持上位性的检测以及测试特定基因之间的相互作用。许多物种的研究结果表明,自然遗传变异之间普遍存在统计上位性。然而,能够分析上位性的实验系统的特性也限制了将这些结果外推回自然群体。
The ability to detect and understand epistasis in natural populations is important for understanding how biological traits are influenced by genetic variation. However, identification and characterization of epistasis in natural populations remains difficult due to statistical issues that arise as a result of multiple comparisons and the fact that most genetic variants segregate at low allele frequencies. In this review, we discuss how model organisms may be used to manipulate genotypic combinations to power the detection of epistasis as well as test interactions between specific genes. Findings from a number of species indicate that statistical epistasis is pervasive between natural genetic variants. However, the properties of experimental systems that enable analysis of epistasis also constrain extrapolation of these results back into natural populations.
