context_page_description: A mixed mating system, also known as “variable inbreeding” a characteristic of many hermaphroditic seed plants, where more than one means of mating is used. Mixed mating usually refers to the production of a mixture of self-fertilized and outbred seeds. Plant mating systems control genetic exchanges within and among individuals, and influence the evolution of plant species through gene flow, which affects the distribution of genetic variation within and among populations. Mixed mating systems are generally characterized by the frequency of selfing vs. outcrossing, but may include the production of asexual seeds through agamospermy. The trade offs for each strategy depend on ecological conditions, pollinator abundance and herbivory and parasite load. Mating systems are not permanent within species; they can vary with environmental factors, and through domestication when plants are bred for commercial agriculture.

Mixed mating usually refers to the production of a mixture of self-fertilized (selfed) and outbred (outcrossed) seeds. Plant mating systems (breeding systems) control genetic exchanges within and among individuals, and influence the evolution of plant species through gene flow, which affects the distribution of genetic variation within and among populations.  Mixed mating systems are generally characterized by the frequency of selfing vs. outcrossing, but may include the production of asexual seeds through agamospermy.  The trade offs for each strategy depend on ecological conditions, pollinator abundance and herbivory and parasite load.
