Summary: At the end of meiosis, 4 daughter cells are formed = eggs or sperm. Each contains half as many chromosomes as the parent cell (n); each cell is genetically different from its parents and from its siblings. Fertilization of an egg by a sperm restores the chromosome number to 2n.
Spermatogenesis is the process in which male haploid germ cells are  produced from diploid spematogonial stem cells by way of mitosis  and meiosis.This occurs in the same â¦ way in rats in the  seminiferous tubules boundaries of the testes.permatogenesis is the process in which male haploid germ cells are  produced from diploid spematogonial stem cells by way of mitosis  and meiosis.
