High diversity but little population subdivision of a lodgepole pine chloroplast DNA polymorphism

We have surveyed a chloroplast DNA restriction fragment length polymorphism in a total of 365 individuals, distributed range-wide in eight natural populations of lodgepole pine (Pinus contorta Dougl.). Six variants were found in the survey, and diversity was high (Hes = 0.44). Population subdivision was weak within and among subspecies (e.g., Fst = 0.04 among subspecies), which is consistent with theoretical predictions for paternally-inherited markers in wind-pollinated outcrossers. Comparison of the chloroplast data with mitochondrial frequency data from the same populations provides evidence that gene flow is differential through seeds and pollen.
