Does focus have an alternation phase in the phase in the same sense as that of octocarpus and laminaria?

Focus, a genus of brown algae, does exhibit an alternation of generations, but its life cycle differs from that of octocarpus and laminaria. While both octocarpus and laminaria have distinct sporophyte and gametophyte phases, focus may present more simplified or varied life cycle stages depending on environmental conditions. Thus, while focus does go through alternation of generations, the specifics of its phases may not parallel the more defined cycles seen in octocarpus and laminaria.
