Explanation / Answer

Since you have posted multiple questions, I am going to answer first four. I hope it helps. Thanks

1. Gametes are defined as the reproductive cells that are responsible for reproduction.

2. Meiosis is a type of cell division. The main purpose of meiosis is to reduce the normal diploid cells to haploid cells, called gametes.

3. Two successive nuclear divisions occur in meiosis which are Meiosis I(Reduction) and Meiosis II(Division). Meiosis produces 4 haploid cells.

4. In human males: Testes

In human females: Ovarian
