Mating System, Effective Density of Pollen Donors and Male Reproductive Variance In the study site, we found a highly significant difference between multilocus and single-locus outcrossing rates ( t m = 0.999 vs. t s = 0.856; Student’s t = 94.466, P <0.001), indicating that about 14% of matings occurred between genetically related plants.
