the cell membranes and cytoplasm of these haploid cells then fuse together in a process known as plasmogamy. this results in a single cell with two nuclei, known as pronuclei. the pronuclei then fuse together in a well regulated process known as karyogamy. this creates a diploid cell known as a zygote, or a zygospore, which can then enter meiosis, a process of chromosome duplication, recombination, and cell division, to create four new haploid gamete cells. one possible advantage of sexual reproduction is that it results in more genetic variability, providing the opportunity for adaptation through natural selection. another advantage is efficient recombinational repair of dna damages during meiosis. thus, karyogamy is the key step in bringing together a variety of genetic material in order to ensure recombination in meiosis.

commelina hockii is an herbaceous plant in the dayflower family found primarily in central africa, from southwestern tanzania in the east, west through the democratic republic of the congo and zambia, and possibly extending further west to angola. the species' distinctive features include its long, tapering spathes with unfused margins, its white flowers, and its many-flowered lower cymes. it can be found in grasslands and "brachystegia"-dominated woodland. it is fairly unusual among "commelina" species in having variation in the color of the antherodes (i.e. non-functional anthers), with some individuals having entirely yellow antherodes, while others contain a dark spot in the center. also, it is one of the only "commelina" species known to leave a papery residue of dried fluid inside its spathes; normally only fused-spathe species are known to produce this substance. only one specimen from angola resembles this species, but it has blue flowers, suggesting it may be a poorly understood and as-yet undescribed separate species. "commelina hockii" is probably closely related to "commelina kituloensis", which shares a similar fruit type, the same tufted perennial habit, similar large spathes with dried fluid substance, and equally numerously flowered inflorescences. that species differs in having purplish flowers, hairy leaves, shorter spathes, and a preference for high altitude grassland.
