Please somebody answer this question: What would a karyotype look like for a person that is diagnosed with down syndrome, and how would that information be helpful to the doctor?? Explain.
(I have no idea why all my questions are being deleted T^T)
To obtain a karyotype, doctors draw a blood sample to examine the baby's cells. They photograph the chromosomes and then group them by size, number, and shape. By examining the karyotype, doctors can diagnose Down syndrome.
