In higher plants the distance to which pollen and seeds are dispersed affects the
frequency of consanguineous matings. In addition, plants are frequently
hermaphroditic and often capable of self-pollination. A single plant may have

For example, Antonovics and Ellstrand (1984) found that the fitness of an
average plant of a minority genotype of a grass, planted amidst large numbers of
another genotype, was twice as great as when it was placed in competition
primarily ...
