The next stage of human evolution

Gattaca anyone?But besides that, what is alarming is the drive to remove all hereditary diseases. I'm not sure I agree with that. Some genetic diseases such as sickle-cell anemia have side affects that give immunity to contagious diseases. For instance Sickle-cell gives those with two dominant (or it is recessive?) alleles complete immunity to malaria. Those with one recessive one dominant have 50% immunity. Those with two recessive have no immunity. What's to say that we have all kinds of similar traits steming from hereditary dieases? We might remove our cure in the search for perfection. Scares me.

i didn't say everything. You sure about homozygous? I recall reading something about alot of adults in Africa with homozygous who were completely immune to malarity.
