Why is meiosis required for germ cell formation, yet is never used by somatic cells?

#Unit 5. Developmental Biology
  1. Meiosis is the cell division process that produces haploid products.

  2. Meiosis is a process that produces one sperm and one egg from each dividing germ cell.

  3. Meiosis is a specialized, highly efficient process of cell division, which is used because of the large numbers of germ cells required by an organism.

  4. Meiosis is a specialized form of cell division that produces four diploid cells instead of just two, facilitating the production of large numbers of germ cells.
