Genetic screening can be used to identify mutant alleles in embryos by analyzing the DNA of the embryo or the parent(s) for the presence of specific genetic variants associated with particular diseases. This information can be used to make decisions about whether to implant the embryo or to pursue alternative options. None of the other options accurately describe the use or requirements of genetic screening.
