Cloning allows you to isolate independent variables for gene study. Additionally, itterated embryo selection is predicated on being able to atleast clone gammetes. Itterated embryo selection need not be so immoral in practice. It also only requires the ability to detect genes for traits, not the ability to modify genes. Thats good since the former is easier than the latter.
