Evolutionary Relationships of Human Populations at the Molecular Level
Relationships between intrapopulational and interpopulational genetic diversity in man
The bottleneck effect (or extended period of reduced population size) is known to increase genetic distance (D) substantially, and this can be a serious factor that disturbs the phylogenetic relationships of populations inferred from genetic distance estimates. The bottleneck effect is also known to be a factor that disturbs the hierarchial relationships of the fixation indices (FST) or the coefficients of gene differentiation (GST) in subdivided…

Estimation of Average Heterozygosity and Genetic Distance From a Small Number of Individuals
The magnitudes of the systematic biases involved in sample heterozygosity and sample genetic distances are evaluated, and formulae for obtaining unbiased estimates of average heterozygosity and genetic distance are developed. It is also shown that the number of individuals to be used for estimating average heterozygosity can be very small if a large number of loci are studied and the average heterozygosity is low. The number of individuals to be …
Molecular Population Genetics and Evolution
Analysis of Gene Diversity in Subdivided Populations
A method is presented by which the gene diversity (heterozygosity) of a subdivided population can be analyzed into its components, i.e., the gene diversities within and between subpopulations. This method is applicable to any population without regard to the number of alleles per locus, the pattern of evolutionary forces such as mutation, selection, and migration, and the reproductive method of the organism used. Measures of the absolute and rela…
Genetic Distance between Populations
A measure of genetic distance (D) based on the identity of genes between populations is formulated. It is defined as D = -logeI, where I is the normalized identity of genes between two populations. This genetic distance measures the accumulated allele differences per locus. If the rate of gene substitution per year is constant, it is linearly related to the divergence time between populations under sexual isolation. It is also linearly related to…
