what is the difference between autogamy and allogamy?

Answer 1

Allogamy is a term used in the field of biological reproduction describing the fertilization of an ovum from one individual with the spermatazoa of another. In humans, the fertilisation event is an instance of allogamy.
By contrast, autogamy is the term used for self-fertilization as in the fertilisation of a flower by its own pollen. In plants, allogamy specifically mean the use of pollen from one plant to fertilize the flower of another plant termed as cross fertilization or cross pollination - pollen exchange between different plant strains or even different plant species (termed as hybridization) .

Answer 2

Self-fertilization (also known as autogamy) occurs in hermaphroditic organisms where the two gametes fused in fertilization come from the same individual. This is common in plants and certain protozoans. The only known naturally occurring, truly self-fertilizing vertebrate is the killifish species Rivulus marmoratus.

Allogamy is a term used in the field of biological reproduction describing the fertilization of an ovum from one individual with the spermatazoa of another. By contrast, autogamy is the term used for self-fertilization. In humans, the fertilisation event is an instance of allogamy. In plants, allogamy is used specifically to mean the use of pollen from one plant to fertilize the flower of another plant and usually syonymous with the term cross fertilization or cross pollination, though the latter term can be used more specifically to mean pollen exchange between different plant strains or even different plant species (where the term cross hybridization can be used) rather than simply between different individuals. Parasites having complex life cycles can pass through alternate stages of allogamous and autogamous reproduction, and the description of a hitherto unknown allogamous stage can be a significant finding with implications for human disease.

Answer 3

autogamy => Self-fertilization in which fission of the cell nucleus occurs without complete cellular division forming two pronuclei so that reunite to form the synkaryon.

allogamy => cross-fertilization in plants

Answer 4

Allogamy - Cross-fertilization in plants
Autogamy - Self-fertilization in plants

Answer 5

Autogamy

Answer 6

MAY B THE SPELLING DIFFERENCE
just kidding
auto means closed and allo means opened up
