Question

You work as a medical professional who identifies abnormalities and diseases early on in babies by testing their genes before they are born. You suspect one of your patients of having Trisomy 13, what test should you perform to be certain?A. DNA profileB. Genetic fingerprintC. KaryotypeD. Missense identification

Answer 1

Trisomy 13, or Patau syndrome, is a syndrome where there is an extra copy of chromosome 13. This causes abnormal development and complex organ defects.

To confirm the diagnosis, a karyotype is done, because it sorts the chromosomes by length, banding pattern, and other characteristics, and allows counting the number of copies of each one.

This means the right answer is C. Karyotype.
