> A low amount of education is not really related to genetics

Intelligence in adulthood is overwhelmingly heritable. Environmental and upbringing effects are small. Twin studies, unrelated sibling studies, etc, demonstrate very large effects.

(Oddly enough, intelligence in childhood does seem to be very influenced by environment, but by adulthood your genetic destiny takes hold).

Intelligence is also the biggest single predictor of your child's educational attainment-- even bigger than SES.

Of course, it's not really clear what one can do with this information that is both ethical and useful.

A confound: severe neglect and abuse is known to permanently reduce intelligence, and this is much less represented in adoption studies because of parental screening and social worker follow-up.
