WebMay 1, 2010 · The μ-Galton–Watson tree is the genealogical tree of a Galton–Watson branching process with offspring distribution μ starting with a single individual called the ancestor. It thus corresponds to the evolution of a population where each individual has, independently of the others, a random number of children distributed according to μ .
