Is it ethical to design a baby by manipulating DNA for hair, eye and skin color?

No, I don't think it's right.

That's the 64 million dollar question! It depends entirely on who you ask.

Personally, I think screen IVF embryos for disorders like type one diabetes and cystic firbrosis is a good idea. Caner genes are harder, because those genes don't mean your child will get caner, just that they're slightly more likely to get cancer. Lifestyle plays a major part in getting cancer or not.

It's gets even fuzzier from there. Is screening babies for homosexual genes ethical? Some would argue it's a disorder, but I strongly disagree.

As yet there's no real way of 'manipulating' DNA to get certain hair or eye colours, but screening can tell you what genes the baby has and giving you the choice to implant the IVF embryo or not.

Physical traits, no. Because then, in each era, every kid would have the "in look" at the time. BORING and weird. Lol. Physical, mental, or health defects yes. If I had a choice between giving my kid a better life or have them be dependent for the rest of their lives, I'd choose to have their DNA altered a little. Interesting question. We had a debate on this in one of my classes. IT WAS HEATED!!!! Lol.
