How many mature egg cells result from meiosis
WebMeiosis happens only with sex cells. (true) The sex cells, sperm or egg, have the same number of chromosomes as all other cells in the body. (false – they have half) Two daughter cells are formed from meiosis. (false - 4 daughter cells) The daughter cells are new sperm and eggs. (True) WebCells reproduce through mitosis to make exact copies of the original cell. This is done for growth and repair. Sexually-reproducing organisms have a second form of cell division that produces reproductive cells with half the number of chromosomes.
