The cell division involved in gamete formation is not of the same type in different organisms. Justify.

Explanation

In a haploid organism, showing haplontic life cycle, gamete formation by mitosis, the diploid zygote formed by the fusion of two haploid gametes undergoes meiosis. In diploid organisms, showing diplontic or haplo-diplontic life cycle, gamete formation by meiosis and haploid gametes are formed, the diploid zygote undergoes mitosis to form diploid individuals.
