New reproductive technologies can raise difficult and troubling questions, including which of the following?

The correct answer is B. To what extent should we select the traits of our children?

This question encapsulates one of the primary ethical debates surrounding new reproductive technologies, particularly in the context of genetic engineering and selective reproduction. It raises concerns about the implications of choosing specific traits, such as intelligence or physical appearance, which can lead to issues of eugenics, social inequality, and the moral ramifications of “designing” a child. While the other options address valid concerns, they are often considered consequences or practical considerations rather than ethical dilemmas central to the discussion of reproductive technology.
