Heterokaryon formation and parasexual recombination between vegetatively incompatible lineages in a population of the chestnut blight fungus, Cryphonectria parasitica.
Evidence of parasexual exchange of DNA in the rice blast fungus challenges its exclusive clonality.

transgenic and transformation methods for directly introducing alien genes to other crop species are not routinely available for introducing alien genes into wheat cultivars.
No process comparable to meiotic sex is known in Bacteria; all genetic exchange occurs by three parasexual
processes that are unidirectional, fragmentary, and infrequent.
The hammam thereby represents a parasexual
space for the unfolding of sexuality, one that helped fix the meaning of sex more than sexual acts themselves.
Also, the parasexual
cycle, in which recombination occurs without meiosis, can function as an alternative for sex in imperfect species (Pontecorvo 1946; Snyder 1961; Davis 1966; Caten 1987).
These mechanisms are completely exclusive of the parasexual
cycle, which has not been demonstrated to occur in nature.
