Abstract

The significance of prezygotic isolation for speciation has been recognized at least since the Modern Synthesis. However, fundamental questions remain. For example, how are genetic associations between traits that contribute to prezygotic isolation maintained? What is the source of genetic variation underlying the evolution of these traits? And how do prezygotic barriers affect patterns of gene flow? We address these questions by reviewing genetic features shared across plants and animals that influence prezygotic isolation. Emerging technologies increasingly enable the identification and functional characterization of the genes involved, allowing us to test established theoretical expectations. Embedding these genes in their developmental context will allow further predictions about what constrains the evolution of prezygotic isolation. Ongoing improvements in statistical and computational tools will reveal how pre- and postzygotic isolation may differ in how they influence gene flow across the genome. Finally, we highlight opportunities for progress by combining theory with appropriate data.

遗传学与受精卵分离的进化。
受精前分离对物种形成的重要性至少从现代合成以来就得到了认可。然而,基本问题仍然存在。例如,导致合子前分离的性状之间的遗传关联是如何维持的?这些特征进化背后的遗传变异来源是什么?受精前屏障是如何影响基因流动模式的?我们通过回顾影响受精前分离的植物和动物之间共享的遗传特征来解决这些问题。新兴技术越来越多地使相关基因的鉴定和功能表征成为可能,使我们能够检验既定的理论预期。将这些基因嵌入它们的发育环境中,将有助于进一步预测是什么限制了受精前分离的进化。统计和计算工具的不断改进将揭示受精前和受精后分离在影响基因组中基因流动方面的差异。最后,我们通过将理论与适当的数据相结合来强调取得进展的机会。
