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 by three different types of life cycles: the haplontic (the being is haploid) haplobiontic (a single type of being) cycle; the diplontic (the being is haploid) haplobiontic (a single type of being) cycle; and the diplobiontic cycle (two types of beings, single haploid and the other diploid). The diblobiontic cycle is called as alternation of generations, or metagenesis. In humans the cycle is diplontic haplobiotic (a single diploid being).
