| − | The n number of a organism (in particular a cell) represents a Haploid count of chromosomes. Cells have a natural number of chromosomes pairs, the number of which is not limited. Being Haploid (one pair) or Diploid (two pairs) or multi-ploid (any number of pairs) is usually regulated by speciation in animals. Plants tend to have species directly related which may have a different ploid and different n numbers. In the case of humans we have 23 homologous chromosomes. | + | The n number of an organism (in particular a cell) represents a Haploid count of chromosomes.
