Question

Why would a karyotype be helpful in diagnosing Turner Syndrome, but ineffective at diagnosing cystic fibrosis?

Answer 1

Karyotype may be defined as the representation of the chromosome according to their size and number. All the chromosomes are represented in the karyotype.

The turner syndrome occurs due to the loss of the one X chromosome. This missing chromosome can easily be noticed in the karyotype. The cystic fibrosis occur due to the mutation of the in the single gene. The single gene mutation cannot be shown by the karyotype.
