haplont

From haploid, ultimately from Ancient Greek ἁπλόος (haplóos, “single, simple”).

haplont (plural haplonts)

1. (biology) Any haplontic organism; any organism whose zygotes undergo zygotic meiosis (meiosis immediately after the fusion of cell nuclei).

     The behavior of haplont Nicotiana glutinosa is in harmony with the foregoing facts. The occurrence of diploid cells in the callus of decapitated haplonts may be attributed to causes similar to those resulting in diploid cells in proximal callus.

   • 1988, Graham Bell, Sex and Death in Protozoa: The History of Obsession, Cambridge University Press, page 12:

     It is thus an amphimictic haplont, but clonal selling gives progeny identical among themselves and with their parents.

     The first transition is a vegetative cell to a gamete, followed by gamete fusion and the production of a zygote. This involves syngamy and in haplont life cycles the 1n gametes fuse to form a 2n motile or non-motile zygote. There can be one stage or two-stage meiosis with resultant haplonts to begin the cycle again.
