Question 5
A test can now show whether a person carries the allele for an inherited condition. Which of these is a genuine concern raised by that ability?
The right answer is the one marked above.
The result could be seen by an employer or an insurer and used against the person. That is a question about privacy and fairness, and the biology cannot settle it.
The other three are the point of the test, not problems with it. Identifying carriers without symptoms is exactly what the Sri Lankan thalassaemia programme is built to do.
