Allogamy is the fertilization of the combination of gametes from two parents, generally the ovum from one individual with the spermatozoa of another. (In isogamous species, the two gametes will not be defined as either sperm or ovum.)

Allogamy is the fertalization of flowers through pollination, this occurs when a flowers ovum is fertalized by a spermatozoa of another flower. Male gametes are found in pollen of plants, the pollen is then carried by a vector which allows the pollen to be transfered to another flower. These vectors that help transfer the pollen can be birds, bees, or bats. Fertalizing begins when the pollen is brought to a female gamete through the pollen tube. This is also known as cross fertalizationtion, in contrast to autogamy wich is self fertalization.
