WitrynaLa meiosis es un tipo de división celular en los organismos eucarióticos que produce la producción de gametos o células sexuales. En los humanos, los gametos son espermatozoides (espermatozoides) en los machos y huevos (óvulos) en las hembras. La característica clave de una célula que ha sufrido meiosis es que contiene un … WitrynaMeiosis. cell division by which gametes, with half the number of chromosomes, are produced. Diploid (2n) → haploid (n) Gametes have half the # of chromosomes. Meiosis is sexual reproduction. Two divisions ( meiosis I and meiosis II ). Sex cells produce gametes (sperm or egg). Occurs only in gonads (testes or ovaries). . WitrynaMeiosis. Meiosis is a type of cell division that results in the formation of four haploid daughter cells from one diploid parent cell. This means that during meiosis the chromosome number in the daughter cells is half of that of the parent cell. Hence this type of division is also known as reduction division. top healing herbs
