Summary

Introduction

William Henry Lang (1923) and Irma Andersson (later Andersson-Kottö; e.g., Andersson, 1923, 1927; Andersson-Kottö, 1929, 1930, 1931) were pioneers in the field of fern genetics. Lang (1923) was the first to demonstrate simple Mendelian inheritance in a fern with his experimental study of the inheritance of entire versus incised leaf margins in Scolopendrium vulgare. Andersson studied inheritance in ferns and was the first to introduce the use of an agar-based growth medium for the experimental study of fern gametophytes (Andersson, 1923). These pioneers paved the way for future explorations of fern and lycophyte population genetics.

In considering how ferns and lycophytes develop and maintain genetic variation, contemporary investigators have used an array of techniques to explore several primary, intertwining topics such as the population genetic implications of reproductive biology (including genetic load), genetic diversity and structure of populations, gene flow and divergence, and the genetics of dispersal and colonization. The goal of this chapter is to review the fern and lycophyte population genetic literature across these broad categories, to provide a synthesis of current knowledge, and to suggest possible future directions of study. We will focus primarily on homosporous taxa because little population genetic research has been conducted on heterosporous taxa.

Population genetics and reproductive biology

An understanding of the reproductive biology of individuals and populations is fundamental for discussing the genetics of populations.
