Sexual reproduction: Involves two parents. Results in offspring that are different from either parent. The genetic variation is due to recombination of chromosomes. This process involves the fusion of two gametes nuclei (egg& sperm). Fusion of the sex cell nuclei occurs during fertilization forming the zygote. Check the details
Facts about meiosis. Meiosis involves two cell division. It produces cells that are different from the parent cell. Each cell has .one-half the number of chromosomes as the parent cell. Meiosis takes place during sexual reproduction, producing sex cells ( eggs & sperms ). It takes place in the sex organs (ovaries & testes) Let…Read more »

As you already know your body is made up of billion of cell-the basic units of structure and function of all living things. Each cell has a cell membrane, that surrounds the cell thus each cell has its own environment. The cell membrane is acting like a guard that identifies what molecules leave or enter…Read more »
