WebMay 1, 2002 · The coalescent is a flexible model that accommodates phenomena such as recombination, age structure, geographical structure and population size change. … Coalescent theory is a natural extension of the more classical population genetics concept of neutral evolution and is an approximation to the Fisher–Wright (or Wright–Fisher) model for large populations. It was discovered independently by several researchers in the 1980s. See more Coalescent theory is a model of how alleles sampled from a population may have originated from a common ancestor. In the simplest case, coalescent theory assumes no recombination, no natural selection, and no See more Coalescents can be visualised using dendrograms which show the relationship of branches of the population to each other.
