Karyogamy does not take immediately after fusion in:
Correct answer: D. All these
- A. Zygomycota
- B. Deuteromycota
- C. Basidiomycota
- D. All these
Explanation
The correct answer is All these because in fungi, karyogamy, the fusion of nuclei, does not occur immediately after the fusion of cytoplasm (plasmogamy) across various groups. In Zygomycota, the zygospore formation involves a resting stage before karyogamy. Basidiomycota is known for its prolonged dikaryotic phase where two nuclei coexist per cell before fusing. Deuteromycota do not typically undergo sexual reproduction, making the question of karyogamy less applicable but still potentially delayed if sexual stages were known.
