What are the three basic sexual life cycles studied in biology? Which of them corresponds to metagenesis? Which of them is the human life cycle?

Sexual reproduction may take place through three different types of life cycles: the haplontic haplobiontic cycle (the organism is haploid, a single type of organism) ; the diplontic haplobiontic cycle (the organism is diploid , a single type of organism); and the diplobiontic cycle (two types of organisms, one haploid and the other diploid). The diplobiontic cycle is known as the alternation of generations, or metagenesis. In humans, the cycle is diplontic haplobiontic (a single diploid organism).
