WebIt is a result of sexual reproduction. Their ascocarps remain underground until some animal digs up for food and scatter the ascospores while devouring the ascocarps. Ascus is usually an elongated sac like structure, which contain normally 8 ascospores. Therefore, the correct answer is option B. Solve any question of Biological Classificationwith:- WebJun 8, 2024 · In each ascus, two or more haploid ascospores fuse their nuclei in karyogamy. During sexual reproduction, thousands of asci fill a fruiting body called the ascocarp. The diploid nucleus gives rise to haploid nuclei by meiosis. The ascospores are then released, germinate, and form hyphae that are disseminated in the environment and start new ...
