Draft:Diplomixis

From Wikipedia, the free encyclopedia

Diplomixis is a process of genetic material mixing between the nuclei of Diplomonads, parasitic organisms that possess two (or more) transcriptionally active nuclei. Presence of the homologous recombination (or template-dependent recombination) machinery and nuclear fusion are the prerequisites for dimplomixis to happen.

Diplomixis is believed to occur in G. duodenalis species and contribute to the parasite's progeny (a) reduced genetic heterozygosity in asexual species,[1][2]

(b) potentially increase the recombination in sexual/recombining strains.[3][4]

More research is needed to elucidate the mechanisms and implications of diplomixis on Giardia genetics and species evolution.
