After fertilization all normal human cells contain the same number of chromosomes as the cells of an adult human - 23 pairs of chromosomes, for a total of 46 chromosomes.
Before fertilization the ovum contains only 23 chromosomes. A second 23 chromosomes are provided by the sperm during fertilization.

∙ 13y agoHumans are diploid. A human somatic cell contains 46 chromosomes: 2 complete haploid sets, which make up 23 homologous chromosome pairs. However, many organisms have more than two sets of homologous chromosomes and are called polyploid.
