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). A karyotype can show different types of mutations, depending on which chromosome it affects.
The extra chromosome 21 material may also occur due to a Robertsonian translocation in 2â4% cases. In this situation, the long arm of chromosome 21 is attached to another chromosome, often chromosome 14. In a male affected with Down syndrome, it results in a karyotype of 46XY,t(14q21q). This may be a new mutation or previously present in one of the parents.
