Question

have a carrier identification test
be tested for PKU
see a genetic counselor
have a carrier identification test, and see a genetic counselor

Answer 1

Answer: The correct answer is the last option.

Explanation:

Carrier identification test is a screening test that tells if a person is carrier of a particular autosomal recessive disease. It helps in determining the possibility of passing that disease to a child.

Genetic counsellor is professional who is expert in human genetics, research, lab work, counselling, et cetera. After the test, it is best to contact a genetic counsellor as he can explain the family pedigree of the disease. He can best explain the probability of passing a genetic disease to the child.
