A cell is diploid if it contains exactly two copies of each chromosome. A cell is haploid if it contains exactly half of a speciesâ typical full set of genetic material. Haploid cells are often used in sexual reproduction. In cells, ploidy defines the number of copies of a chromosome found within the cell. The number of the basic set of chromosomes is described as the monoploid number. Most cells within a human (and other animals) are diploid, which means they have two copies of each chromosome.
Diploid cells contain two complete sets (2n) of chromosomes. Haploid cells have half the number of chromosomes (n) as diploid-i.e. a haploid cell contains only one complete set of chromosomes.
