WebFungi have a distinctive life cycle that includes an unusual 'dikaryotic' or 'heterokaryotic' cell type that has two nuclei. The life cycle begins when a haploid spore germinates, dividing mitotically to form a 'multicellular' haploid organism (hypha). In most fungi, hyphae can produce spores directly, through an asexual process (mitosis). ...

WebWhen a pair of sexually compatible homokayons merge they produce heterokaryotic mycelia in which each hyphal compartment contains a pair of nuclei, one derived from each mate. Compatibility is determined by mating type genes (Chapter 4). The terms dikaryon and dikaryotic mycelium are also used to describe these colonies.

Special dikaryotic ascogenous (ascus-producing) hyphae arise from this dikaryon, in which each cell has pairs of nuclei: one from the “male” strain and one from the “female” strain. In each ascus, two haploid nuclei fuse in karyogamy.

WebIn the sexual phase, plus and minus haploid mating types conjugate to form a heterokaryotic zygosporangium. Karyogamy then produces a diploid zygote.
