WitrynaIn animals, haploid cells containing a single copy of each homologous chromosome are found only within gametes. Gametes fuse with another haploid gamete to produce a diploid cell. The nuclear division that forms haploid cells, which is called meiosis, is related to mitosis. http://www.differencebetween.info/difference-between-meiosis-in-plant-and-animal-cells
