I think a lot of wealthy people will throw money at genetic snake oil. Traits are determined by multiple genes (e.g. eye or hair colour), and single genes control multiple traits (e.g. EDAR gene which is associated with thick hair, small breasts, and shovel-shaped incisors). Sometimes genes for less desirable traits (e.g. mental illness, sickle cell anemia) may be associated with desirable traits (higher intelligence, resistence to malaria).
