The human karyotype contains 22 pairs of autosomal chromosomes and a pair of sex chromosomes. The normal karyotype for a female contains a pair of X chromosomes, whereas the normal karyotype for a male contains an X and a Y chromosome [1]. Variations in the human karyotype can lead to genetic disorders such as Down's Syndrome or Klinefelter's Syndrome.
