Well, some basic gene selection is already happening. I know that they can diagnosis embryos with trisomy 21 and than implant the ones that are not affected, but that is on the chromosomal level, not the genetic level. I am not sure how you would select for a trait that is created by multiple genes (like height and eye color). And most traits that babies have the potential to develop are influenced by environment (e.g. very premature babies usually don''t get adequate nutrition during their NICU course and that will affect their growth potential). There is no amount of genetic manipulation that can control for the environment they will grow up in.
