    As stated before, they are arranged in homologous pairs with length descending, ending in the x- and y-chromosomes. The y-chromosome is slightly shorter than the x and helps determine the sex. Also karyotypes are use in mapping specific chromosal deletions or additions, such as in Trisomy-21 or down syndrome.

    They are arranged in homologous pairs longest to shortest.
