In this chapter, we explore the connections between two areas of probability: percolation theory and population genetic models. Our first goal is to highlight a construction on Bienaymé-Galton-Watson trees, which has been described in two different ways: as Bernoulli bond percolation and as neutral mutations. Next, we introduce a novel connection between the Divide-and-Color percolation model and a particular multi-type Bienaymé-Galton-Watson tree. We provide a gentle introduction to these topics while presenting an overview of the results that connect them.

摘要

In this chapter, we explore the connections between two areas of probability: percolation theory and population genetic models. Our first goal is to highlight a construction on Bienaymé-Galton-Watson trees, which has been described in two different ways: as Bernoulli bond percolation and as neutral mutations. Next, we introduce a novel connection between the Divide-and-Color percolation model and a particular multi-type Bienaymé-Galton-Watson tree. We provide a gentle introduction to these topics while presenting an overview of the results that connect them.
