Blaming it on genetics only applies when discussing inbreeding.

Why is that?

Is anybody seriously contending that in this country rich people are on average of higher IQ than poor people? Really?

Since we know IQ is at least 50% hereditable, wouldn't we expect this correlation?

The cool thing about sex vs cloning is that two really smart people can produce a complete moron and vice versa.

I think the main factor is pre- and post-natal care. And the post-natal goes all the way to the teenaged years. It includes not just a proper diet but the best training.

i.e. take an illegitimate baby from a dirt poor mom that at least gave it good pre-natal care, adopt it out to a well off and caring family, and you could end up with a VERY intelligent individual in adulthood.

I’ll take it a step further: I noticed that when I moved from Seattle to central KY that the people in KY were noticeably uglier. But on closer examination I realized it was mostly because of two things:

1. Diet - there are a LOT more fat people here.
2. Lack of good hairdressers, money for stylish clothing, or motivation to make yourself look nice.

Last time I looked at the data, the studies seemed to indicate between 2/3 & 3/4 heredity. But be that as it may.

The Left has to embrace the make-believe world of human interchangeability in order to keep their grievance (Blame & Envy) explanation for inequality, viable. Once you recognize that most high achievers deserve to be high achievers, and are not exploiting those who are not, the whole rationalization for turning society upside down by bureaucratic intervention, crumbles in the dust where it belongs.
