Identity by descent in island-mainland populations
Article Abstract:
A stochastic birth, death and immigration (BDI) model helps explain the genetic structure in island-mainland populations having continuous overlapping generation and fluctuating population sizes. An equation derived using the BDI model connects the average probability of identity by descent (fo) to birth-rate of individuals, arrival rate of immigrants and probability of IBD for two immigrants. Time and death processes exert no influence on fo and genetic differentiation among island populations.

The pattern of neutral molecular variation under the background selection model
Article Abstract:
A study was conducted to examine the behavior of genetic diversity at a neutral locus in a genomic region without recombination, but subject to selection against deleterious alleles maintained by mutation using stochastic simulations of the infinite sites model. It focuses on determining the effect of background selection on determining the number of segregating sites.
