Name the stages of alternation of generations. Specify whether the stage is diploid or haploid

The alteration of generation is also called metagenesis. Haploid and diploid both stages are multicellular. Here both may be dominant to various types of degree but in different species. Meiosis and fertilization separate the organism's development into two. The two stages are different genetically. This cycle happens in plant and some different types of algae. About all animal have diploid-dominant cycle in which gametes are only haploid. Most fungi and some protists have haploid dominant cycle. In this cycle, the body of the organism become mature.
