The Important Concept of Molecular Ecology--Genetic Distance and Its Measuring
分子生态学重要概念——遗传距离及其测度的理论研究概况

Genetic distance is the extent of gene differences between populations or species that is measured by some numerical quantity. The statistical and genetic properties of several typical distance measures will be classified into two groups, i. e., measures for population classification and measures for evolutionary study. Several basic mutation models, such as the infinite alleles mutation model, the stepwise mutation model, the mutation in nucleotide sequences model and so on, together with some parameters and their statistics relating to genetic distance, are reviewed too. Authors suggest that suitable models and software packages should be chosen before analyses of all types of molecular data.
