The paper investigates how deleterious mutations, dominance, and gene flow affect neutral genetic variation in structured populations using simulations and genealogical analyses.

The paper models interactions between reproductive isolation mechanisms and finds local adaptation is the most effective barrier, with other mechanisms evolving depending on migration rates.

The paper investigates how a genetic barrier to gene flow can strengthen or weaken in parapatric speciation through the accumulation of Dobzhansky-Muller incompatibilities.
