question:  What is main the flaw in Harris' plan to sell the eggs of fashion models?
context: This week, soft-porn entrepreneur Ron Harris began auctioning the eggs of fashion models on the Internet. Egg auctions will produce designer babies. Harris cites his experience as a horse breeder and asks, "We bid for everything else in this society--why not eggs?" Alarmists, agreeing that Harris "can put you into your own designer baby by selling eggs," predict that his success will steer "the future of human breeding" toward "genetic engineering." 2. Egg auctions will fail to produce designer babies. While fretting about what will happen if Harris succeeds, fertility experts simultaneously debunk that scenario. First, the child of an ugly man and a pretty woman is just as likely to be ugly as to be pretty. Second, everyone carries "recessive" genes, which are invisible in this generation but may become visible in the next. This site simply mirrors our current society, in that beauty usually goes to the highest bidder." 4. Egg auctions will promote the survival of the unfittest. Harris writes that only men with "substantial financial resources" are fit to give his models' offspring "a financially secure and stable life." But skeptics wonder whether women who sell their eggs to the highest bidder--and men who buy these eggs for the sole purpose of spawning good-looking children--may produce children just as dysfunctional as themselves. Egg auctions will fail to promote the survival of the unfittest. A model who is perfectly ruthless will conceal this fact when selling her eggs. (One of Harris' "angels" has already been caught lying about her age.) How does Harris know whether his models have had collagen injections and nose jobs? Annas concludes that since there's "no way to know how much of their beauty is a product of their genes, plastic surgery, a makeup artist, or exercise," only a "naive" person would buy their eggs on the basis of the photographs displayed on the site.
output:  He doesn't take into account recessive genes.
options:  He doesn't take into account the IQ of the donors.  He doesn't take into account recessive genes.  He doesn't screen the eggs for genetic problems.  He doesn't take the medical history of the donors.
