Which of the following statements regarding the life cycle of Selaginella is INCORRECT?
The megaspores and microspores germinate to give rise to female and male gametophytes, respectively.
The development of the zygote into the embryo takes place within the female gametophyte, which is independent of the sporophyte.
The sporophyte is the dominant phase in the life cycle.
Selaginella exhibits heterospory.
