Which of the following sequences describes sexual reproduction in the fungal life cycle? Free-swimming gametes fuse to form a diploid zygote, which grows by mitosis. Diploid spores divide by meiosis to form haploid gametes, which join to form mycelia. The haploid zygote divides by meiosis to form haploid spores. The diploid zygote divides by meiosis to form haploid spores, which produce haploid mycelia through mitosis. Haploid gametes divide by meiosis to produce a diploid zygote, which grows by mitosis to produce diploid mycelia.
