Exempel på hur man kan använda ALLOGAMY i en mening

• Self-incompatibility (SI) is a general name for several genetic mechanisms that prevent self-fertilization in sexually reproducing organisms, and thus encourage outcrossing and allogamy.
• It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population.
• In plants, allogamy is used specifically to mean the use of pollen from one plant to fertilize the flower of another plant and usually synonymous with the term "cross-fertilization" or "cross-pollination" (outcrossing).
• The most common form of androdioecy in animals involves hermaphrodites that can reproduce by autogamy or allogamy through ovum with males.
• The majority of monocots are animal pollinated (zoophilous), Monocots have mechanisms to promote or suppress cross-fertilization (allogamy) and self-fertilization (autogamy or geitonogamy).
• Explaining this situation also reveals the advantages of domesticated plants at this time: the vegetative cycle of trees, which meant waiting several years after planting before becoming productive, whereas cereals and legumes became productive the year they were planted; tree pollination, which is generally by cross-fertilization (allogamy), is complex to control, as it requires at least mastery of cuttings and layering to multiply, whereas cereals and legumes reproduce by self-fertilization (autogamy) and only need to be sown to grow.
