When a haploid sperm cell and a haploid egg cell fuse at fertilization, the genetic information is determined for that organism at that moment. After fertilization occurs, a diploid body cell is the result and  mitotic cell division will take place, resulting in the formation of daughter cells. After each mitotic division, the genetic information is replicated and passed down to each daughter cell. Therefore, all the cells in body, also known as somatic cells are diploid and contain the exact chromosome compliment as that original fertilized egg cell. The only cells in a sexually reproducing organism that have a different number of chromosomes are the gametes or sex cells. These have half the chromosome complement of the organism that is reproducing, or the haploid number of chromosomes.
