分子生态学重要概念——遗传距离及其测度的理论研究概况

综述了遗传距离的概念、背景，有关遗传距离的几种基本的突变模型以及和遗传距离有关的参量和几种常用统计量，指出在处理蛋白质数据、分子数据以及序列数据时，如何选择相应的统计量和可用的软件包，同时还着重指明了各种模型的假设前提，为处理实际的蛋白质或分子数据时选择合适的模型，和对数据的最终解释提供一些帮助。

The Important Concept of Molecular Ecology--Genetic Distance and Its Measuring

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.
