How many haploid cells does corn have
WebNearly all animals have a diploid-dominant life cycle in which the only haploid cells are the gametes. Early in the development of an animal embryo, special diploid cells, called germ cells, are made in the gonads (testes and ovaries).Germ cells can divide by mitosis to make more germ cells, but some of them undergo meiosis, making haploid gametes (sperm … Web21 nov. 2009 · Given, 2n=20, Since a mother cell divides into four haploid (n) daughter cells.
