what's a diploid
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.
