Multispecies coalescent process

Quality 0.00 · 0 views · Updated 1 month ago

Multispecies Coalescent Process is a stochastic process model that describes the genealogical relationships for a sample of DNA sequences taken from several species. It represents the application of coalescent theory to the case of multiple species. The multispecies coalescent results in cases where the relationships among species for an individual gene (the gene tree) can differ from the broader history of the species (the species tree). It has important implications for the theory and practice of phylogenetics and for understanding genome evolution.
