About Lesson
- Plant species where normal mode of seed set is through a high degree of cross-pollination have characteristic reproductive features and population structure.
- Existence of self-sterility, self-incompatibility, imperfect flowers, and mechanical obstructions make the plant dependent upon foreign pollen for normal seed set.
- Each plant receives a blend of pollen from a large number of individuals each having different genotypes.
- Such populations are characterized by a high degree of heterozygosity with tremendous free and potential genetic variation, which is maintained in a steady state by free gene flow among individuals within the populations.
