Given the predominance of outcrossing by angiosperms, large costs must often overwhelm the genetic benefit of selfing derived from contributing two haploid genomes to each off-spring rather than one. In addition to the well-studied genetic cost of inbreeding depression, selfing imposes a mating cost whenever self-pollination reduces opportunities for pollen export. Because self-pollination is a heterogeneous process, pollen discounting and its evolutionary consequences vary with pollination… CONTINUE READING
