Diploid cells, or somatic cells, contain two complete copies of each chromosome within the cell nucleus. The two copies of one chromosome pair up and are called homologous chromosomes. Human diploid cells consist of 46 chromosomes which include all cells, with the exception of gamete cells containing half of the required genetic information and are referred to as Haploid. Any cell with homologous chromosomes is said to be diploid. The diploid number of a cell is commonly abbreviated to 2n, where n is the number of chromosomes. Diploid cells are produced by mitosis and the daughter cells are exact replicas of the parent cell. Examples of diploid cells include skin cells and muscle cells.
