Biology · BIOLOGICAL CLASSIFICATION

Regarding the site of meiotic reduction division and spore release in Basidiomycetes, which statement is factually precise?

1. Karyogamy and meiosis take place inside the basidium, producing four basidiospores exogenously on the basidium
2. Karyogamy occurs in somatic hyphae, while meiosis occurs in the ascocarp yielding eight endospores
3. Karyogamy and meiosis occur within an unbranched sporangium, releasing aplanospores endogenously
4. Meiosis occurs prior to plasmogamy, leading to the exogenous cleavage of diploid conidiophores
