Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDF- Karyogamy is the process in which the two nuclei of the dikaryon cell fuse in the basidium of Agaricus (mushroom). This results in the formation of a diploid nucleus, which is a crucial step in the sexual reproduction of fungi.
- In Agaricus, the dikaryotic stage is characterized by cells that contain two genetically distinct nuclei. These nuclei eventually fuse during karyogamy to form a single diploid nucleus, which then undergoes meiosis to produce haploid spores.
- Polygamy refers to a mating system in which an individual has multiple partners. This term is not related to the fusion of nuclei in fungi.
- Pseudogamy is a form of reproduction that involves the fusion of gametes without the fusion of their nuclei. This term is not applicable to the process occurring in the basidium of Agaricus.
- Somatogamy refers to the fusion of somatic cells rather than gametes. While it involves cell fusion, it is not specific to the nuclear fusion process in the basidium of fungi.
