The relative importance of factors determining genetic drift: mating system, spatial genetic structure, habitat and census size in Arabidopsis lyrata
Willi Y and Maattanen K. 2010. The relative importance of factors determining genetic drift: mating system, spatial genetic structure, habitat and census size in Arabidopsis lyrata. New Phytologist. 188:1-10
The contributions of several population-level features to genetic drift in 18 populations of Arabidopsis lyrata were estimated. The factors were outcrossing rate, within-population spatial genetic structure, census size and substrate type. The expected heterozygosity at 10 microsatellite loci was taken to reflect the effective population size and strength of genetic drift. The mating system explained most of the variation in heterozygosity , followed by substrate, genetic structure and census size.
