> Nucleus also provides probability assessments for the embryos’ IQ, height and eye color. Sadeghi said that Nucleus informs customers of the strength of the various predictions. IQ predictions are limited in accuracy, according to the company.
On top of that you have recessive genetic traits as well which means you can get stuff like skin, hair and eye color that "pause" sometimes over generations. Used to be quite a source of infidelity allegations until Mendel's inheritance research, and frankly it's still something that pops up even today.
If we take 100 embryos and we both predict their heights and IQs at 18, you with only biological sex and me additionally with the heights and IQs of the parents, I will wager a large sum that my predictions will be better than yours.
Are you interested in taking the other side of that bet for even money? I’ll even give you +110 odds to ensure you have a sportsbook-sized edge if there’s no predictive value.
Even twins raised in totally separate households will have very similar IQs later in life.
This epigenetic stuff is invariably copium from people who don’t want to admit their intellectual gifts are in fact gifts and as a corollary, all the downstream economic rewards of intelligence are also mere gifts from the lottery of being born to high-IQ parents.
The explanation seems to be that whatever random genes you got to have an off-average IQ score cancel out with your partner and your offspring then regresses to the mean.
