I think it is interesting to look at the cloning case and examine its ethical implications regarding testing for genetic disorders. When discussing Allhoff's argument against current cloning cases he discovers that due to the shortening of telomerase from replications, creating a clone would be deliberately allowing that clone to live a shorter life and be subject to many of the degenerative diseases that come from old age such as various cancers, Alzheimer's disease, and others. In the case of Dolly the sheep clone, she lived for half the life of an average sheep because her cells were taken from a 7-year old sheep. Therefore, Allhoff believes that cloning is immoral and unjustified right now because of its effects on the clone.
I believe that according to these guidelines, it is immoral for parents to avoid genetic testing for diseases such as Huntington's disease, because if they abstain they did not take any preventative measures to keep that child from the pain that may come from a genetic disease. Although Allhoff disagrees with Principle Q, if you have the choice between having two children (at different times, with different people) you ought to choose the time or partner that will provide the child that is better off, he thinks that reproduction is not only aimed to maximize the child's welfare, but instead to create the best child they are able to. However, there are many tests now along with genetic engineering that would allow parents to craft the best child they are able to and therefore they may be morally required to take such genetic tests in order to create the best child that they can and ensure they will not face extreme hardships such as Huntington's disease. This may be difficult for some parents to face because it is not definite that a child will get these diseases, yet sometimes the chance is as high as 50%. If a couple discovered that their child was at higher risk for a genetic disease, the only moral choice would be to abstain from having a child. However, many parents do not want to make this discovery because they want to raise a child and many would take the risk.
Do you think it is moral for a parent to have a child when they have a risk of a genetic disease? Along those lines, do you think parents need to participate in genetic testing before they are allowed to have a child?
