The effect of gene flow on the coalescent time in the human-chimpanzee ancestral population.

Abstract excerpt

The coalescent process in the human-chimpanzee ancestral population is investigated using a model, which incorporates a certain time period of gene flow during the speciation process. a is a parameter to represent the degree and time of gene flow, and the model is identical to the null model with an instantaneous species split when a=infinity. A maximum likelihood (ML) method is developed to estimate a, and its...
