Question

Quizplus · Accepted Answer

In alternation of generations, the organism alternates between a haploid (gametophyte) and diploid (sporophyte) phase. The correct sequence of events is gametophyte (haploid) → gamete (haploid) → fusion → sporophyte (diploid) → spore (haploid) → gametophyte (haploid). This is the sequence described in option A. Option B has the order of events reversed, option C has the fusion occurring before the gametophyte and option D has the sporophyte forming before the spore.
