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.
The divisions of meiosis. Meiosis [meiosis: type of cell division which forms sex cells (gametes) each with half the usual number of chromosomes] is the type of cell division by which gametes [gametes: the sex cells-sperm in males, ova (eggs) in females] , are produced.ack.
