Gametic meiosis: When the reproductive cells of a diploid organism undergoes meiosis to produce haploid gametes, it is called gametic meiosis.
Zygotic meiosis: Some algae and fungi are haploid adults. They produce haploid gametes which upon fertilization form a diploid zygote. This zygote undergoes meiosis to form haploid spores, which on repeated mitotic division form the adult body.
