Bring population mansion based on STR variation within Y-chromosome SNP-haplogroups

Motivation: Dating divergence within- and between DNA-lineages is of great importance for revealing historic information from observed DNA variation in human populations. The increasing amount of data on Y-chromosome SNI's and STRs require adequate methods for estimation of population expansion time. Such methods should necessarily involve mathematical models that describe evolution of DNA variation, and statistical methods to estimate the dates of population events. Results: Dynamic models of population divergence under mutation, genetic drift and migration are analyzed. Estimates of the dynamic parameters are introduced and applied to several data sets on worldwide human populations.
