Question

in the life cycle of fungi and some protists, which of the following processes leads to the formation of gametes?
◯ meiosis in the diploid zygote
◯ mitosis in the haploid unicellular or multicellular organism
◯ meiosis in the haploid unicellular or multicellular organism
◯ mitosis in the diploid zygote

Explanation:

In the life cycle of fungi and some protists, meiosis occurs in the diploid zygote. Mitosis is for growth and asexual reproduction in somatic cells. Meiosis in haploid organisms (unicellular or multicellular) would not lead to gamete formation as they already have the haploid number. Mitosis in diploid zygote would just produce more diploid cells (for growth if it were a multicellular organism's zygote in a different life - cycle context). But in fungi and some protists, the diploid zygote undergoes meiosis to form haploid cells which can act as gametes.

Answer:

meiosis in the diploid zygote
