WebJul 15, 2024 · Placing the coalescent in the context of a species phylogeny makes it possible to use the ever-increasing genomic sequence data from multiple species to address a number of important biological questions, and in the past two decades, the MSC has emerged as the natural framework for such inferences. The probability density of the gene trees under the multispecies coalescent model is discussed along with its use for parameter estimation using multi-locus sequence data. In the basic multispecies coalescent model, the species phylogeny is assumed to be known.
