Meosis |
| Answer» Meiosis\xa0is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our *** cells – sperm in males, eggs in females. During\xa0meiosis\xa0one cell?\xa0divides twice to form four daughter cells.\xa0Meiosis\xa0mainly takes place in sperm cell (male) and in egg cell (female). In the male,\xa0meiosis\xa0takes place after puberty. Diploid cells within the testes undergo\xa0meiosis\xa0to produce haploid sperm cells with 23 chromosomes.\xa0In multicellular plants and animals, however, meiosis is restricted to the germ cells, where it is key to sexual reproduction. Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce\xa0haploid\xa0gametes (the sperm and the egg). | |
