Question
The mother becomes pregnant again. Amniocentesis shows that the fetus has a Y chromosome. The parents want to know whether the child will be affected. You conduct a PCR analysis of the disease gene of cells from the fetus. What are the possible results, and what will you tell the parents?
** I know that If the child has the 300 base pair product, he will not be affected. If he has the 330 base pair product, he will be affected. But please explain more in depth. (THE PREVIOUS CHEGG ANSWER IS INCORRECT)
Explanation / Answer
This question might be missing some information.
The disease gene is represented by the 330 base pair DNA segment. So, if the 330 gene segment is found, then it can be concluded that the child will be affected with the disease.
