a gamete -either sperm or egg - has 23 chromosomes.  They were separated from their homologous partners during meiosis  The end result of meiosis = 4 haploid sex cells with 23 chromosomes each - half the chromosomes of a body cell.  When the sperm cell with 23 chromosomes pairs up with an egg cell with 23 chromosomes you get a 46 chromosome zygote.
