Estimation of genetic distance and coefficient of gene diversity from single-probe multilocus DNA fingerprinting data.

abstract：:In phylogenetic inference, an evolutionary model describes the substitution processes along each edge of a phylogenetic tree. Misspecification of the model has important implications for the analysis of phylogenetic data. Conventionally, however, the selection of a suitable evolutionary model is based on heuristics or...
