Both male and female gametes are created during the process of meiosis. the formation of male gametes or sperm is called spermatogenesis. after telophase ii of spermatogenesis, there would be male gametes created that are all genetically

There would be 4 sperm or haploid cells that are genetically identical.

Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. Meiosis I like mitosis is the cell division that produces diploid cells. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number.  

They both determine the exact age of rocks.
