Solution
| Gametic meiosis | Zygotic meiosis |
| When the reproductive cells of a diploid organism undergoes meiosis to produce haploid gametes, it is called gametic 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. |
