A karyotype tells you if you have the normal ammont of chromosomes (46 for humans), it can also tell you if you have more or less and if this is the case what it is that you have. The most common syndrome would be Down Syndrome, or trisomy 21. Down Syndrome is also called trisomy 21 because if you look at a karyotype from someone that has this syndrome then they have three coppies of the 21st chromosome.

What is a karyotype and what type of mutation does it show?

A karyotype is a picture of the chromosomes in a cell. 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.
