Question

Which process is adopted by organisms with a haplontic life cycle for the division of the zygote?

Answer 1

Meiosis:

1. The zygote divides via meiosis in organisms with a haplontic life cycle.
2. In an organism with a haplontic life cycle, zygotic meiosis occurs, in which the zygote undergoes meiosis to create haploid spores, which divide mitotically to form the gametophyte.
3. The diploid stage is merely the zygote (2n) in such organisms during their whole life cycle, and the haploid stage (gametophyte) takes dominance.
