An approach to the coalescent, the fractional coalescent (-coalescent), is introduced. The derivation is based on the discrete-time Cannings population model in which the variance of the number of offspring depends on the parameter. This additional parameteraffects the variability of the patterns of the waiting times; values oflead to an increase of short time intervals, but occasionally allow for very long time intervals. When, the-coalescent and the Kingman’s-coalescent are equivalent. The distribution of the time to the most recent common ancestor and the probability thatgenes descend fromancestral genes in a time interval of lengthfor the-coalescent are derived. The-coalescent has been implemented in the population genetic model inference software Migrate. Simulation studies suggest that it is possible to accurately estimatevalues from data that were generated with knownvalues and that the-coalescent can detect potential environmental heterogeneity within a population. Bayes factor comparisons of simulated data withand real data (H1N1 influenza and malaria parasites) showed an improved model fit of the-coalescent over the-coalescent. The development of the-coalescent and its inclusion into the inference program Migratefacilitates testing for deviations from the-coalescent.
