Agamogamy
Definition
A mode of reproduction within which a structural alternation occurs between two different asexual phases, completely excluding the gametic fusion stage or the genetic recombination specific to sexual reproduction. This rare biological phenomenon ensures the perpetuation of the species through purely mitotic or sporogenic multiplication cycles, found in certain protozoans and unicellular organisms adapted to isolated ecological niches.
