Q

Describe the Halplodiplontic life cycle.

A

Gametophytes generation which is the egg and sperm go through fertilization which produces a diploid zygote (mitosis). The zygote becomes the sporophyte generation which produces the spores and the spores go through meiosis and become the gametophyte generation once again.
