Heterosis just means there are twice as many factors to worry over. If it becomes too faddish to pick the exact same two genetic codings for a particular gene or select away every gene not on a preferred list, we still lose and immense amount of variability within a generation. The ultimate end is not even to simply pick the contents of the 46 chromosomes. It is medically plausible to purposefully create human chimeras -- basically it when fraternal twins happen to combine to become one fetus. ("We have selected these 46 chromosomes for the neural material, and these other 46 for the skeletal-muscular system. Looks like we have a few fetuses where the combination took to the right locations. We destroyed many eggs, but it is all worth it so your son can be the best, right?") |
