You can use other nations if they currently have this program in place. You cannot use other nations that have dynamically different cultures to demonstrate how our culture will work.
Even if we pretend that there would be a premium on boys in this nation, all that will do is make women more valuable and the pendulem will swing in the opposite direction resulting in a balance between males and females.
I just want to try and nip a lot of these extreme examples in the butt before they are proposed with seriousness. We are not talking about a single governmentally approved list of genetic codes, nor are we talking about allowing people to select from a bank. I’m talking about a mother and father going to the doctor, having the child screened genetically for abnormalities and, at the same time, having the doctor tweak certain features like having the child have the mother’s eyes or the father’s chin, etc.
No body sculpting. No brain enhancements. No eyes with reflective surfaces like cats to provide for night vision. No third lungs so they can stay under water longer. No extra 4 arms to make them spiderlike.
