Step-by-step solution
The alternation of the two phases of life cycle between sexual phase and asexual phase is called alternation of generation. Such life cycle pattern is commonly observed in plants and algae. It is also called metagenesis and in it haploid gametophytic (generally sexual) generation alternates with diploid sporophytic (generally asexual) generation. There are three variations in the life cycle. In diplontic life cycle, the sporophyte is diploid, dominant, autotrophic and independent. The gametophytic generation is hap
