群体遗传学:面向物理学家的导论

Population genetics: an introduction for physicists

Andrea Iglesias-Ramas, Samuele Pio Lipani, Rosalind J. Allen

AI总结:

本文面向物理学家系统介绍群体遗传学,涵盖生物学背景、自然选择、孟德尔遗传、变异维持、突变选择及 Wright-Fisher 随机模型。

摘要:

群体遗传学处于演化理论的核心。这一主题构成了许多生物科学课程的一部分,但很少向物理专业学生讲授。由于物理学家对生物演化的兴趣日益浓厚,我们旨在提供一份为物理学家撰写的群体遗传学简要导论。我们从两个背景章节开始:第1章简要介绍该主题的历史,第2章提供一些必要的生物学背景。主要内容从第3章开始,该章讨论达尔文自然选择与孟德尔遗传背后的关键概念。第4章介绍种群中变异如何得以维持的基础知识,第5章讨论突变与选择。在第6章中,我们以 Wright-Fisher 模型为例讨论群体遗传学中的随机效应;最后,在第7章中给出结论性思考,并列出一些优秀教科书的参考文献。

英文摘要:

Population genetics lies at the heart of evolutionary theory. This topic forms part of many biological science curricula but is rarely taught to physics students. Since physicists are becoming increasingly interested in biological evolution, we aim to provide a brief introduction to population genetics, written for physicists. We start with two background chapters: chapter 1 provides a brief historical introduction to the topic, while chapter 2 provides some essential biological background. We begin our main content with chapter 3 which discusses the key concepts behind Darwinian natural selection and Mendelian inheritance. Chapter 4 covers the basics of how variation is maintained in populations, while chapter 5 discusses mutation and selection. In chapter 6 we discuss stochastic effects in population genetics using the Wright-Fisher model as our example, and finally we offer concluding thoughts and references to excellent textbooks in chapter 7.
