Meiosis is nothing but cell division in which a single cell divides twice to form four cells containing half the original amount of genetic information.
Gametogenesis refers to the production of gametes from haploid precursor cells.
Meiosis is required for gametogenesis.
Meiosis is the process of cell division whereas gametogenesis is the process of gamete formation.
Gametogenesis occurs through meiosis to form haploid gametes.
Male gamete and female gamete both are haploid and they fuse together during syngamy to restore the DNA content in the offspring.
In this way, the total chromosome number in a cell remains constant over generations.
