Next, we … The parasexual cycle resembles sexual reproduction. In both cases, unlike hyphae (or modifications thereof) may fuse (plasmogamy) and their nuclei will occupy the same cell. The unlike nuclei fuse (karyogamy) to form a diploid (zygote) nucleus. See more The parasexual cycle, a process restricted to fungi and single-celled organisms, is a nonsexual mechanism of parasexuality for transferring genetic material without meiosis or the development of sexual structures. It was … See more The potential to undergo a parasexual cycle under laboratory conditions has been demonstrated in many species of filamentous fungi, including Fusarium monoliforme, See more Diploidization Occasionally, two haploid nuclei fuse to form a diploid nucleus—with two homologous copies of each chromosome. The mechanism is largely unknown, and it seems to be a relatively rare event, but once a diploid … See more Parasexuality has become a useful tool for industrial mycologists to produce strains with desired combinations of properties.
