For example, a human cell has 46 chromosomes. In the karyotype, 23 pairs of chromosomes will be shown (23 x 2 = 46). A karyotype can show different types of mutations, depending on which chromosome it affects.For example, Down Syndrome is a trisomy in chromosome 21, so there will be THREE instead of two chromosome 21s. You can research more mutations shown by chromosomes in a karyotype.or example, a human cell has 46 chromosomes. In the karyotype, 23 pairs of chromosomes will be shown (23 x 2 = 46).

The normal human karyotypes contain 22 pairs of autosomal chromosomes and one pair of sex chromosomes. Normal karyotypes for females contain two X chromosomes and are denoted 46,XX; males have both an X and a Y chromosome denoted 46,XY.Any variation from the standard karyotype may lead to developmental abnormalities.ormal karyotypes for females contain two X chromosomes and are denoted 46,XX; males have both an X and a Y chromosome denoted 46,XY.
