FAQ
Frequently Asked Questions
Very closely related. Cross-pollination is the transfer of pollen, while allogamy specifically refers to the fertilization event resulting from that cross-pollination.
No, the term is strictly for plants and some fungi/algae. The equivalent concept in animals is usually called outbreeding or cross-breeding.
Autogamy, which is self-fertilization within the same flower or individual.
It is crucial for the yield of many crops (e.g., kiwi, cherries) that cannot self-pollinate. Understanding it guides planting strategies and pollinator management.

Learning
Memory Aids
Mnemonic
Think 'ALLO' as in 'other' (like 'allophone' = other sound) + 'GAMY' as in marriage/union. It's marriage/union with another.
Conceptual Metaphor
REPRODUCTION IS A UNION; GENETIC DIVERSITY IS HEALTH.
