If both parental DNA contribute numbers ( which are low in value) or both parental DNA contribute multipliers in the INT chromosome then the offspring will be low on intelligence.
This applies regardless to the race, they could be white or black, the result is the same.
I’m not sure one can compare a packet of seeds to human beings.
The make-up of a human entity is exceptionally more complex and layered than a seed.
This would be like comparing a person to something akin to a potato or a daffodil.
Decades of scientific research in Europe, America, Australia, New Zealand alone have all produced the same results. That one inherits everything from ones DNA, it’s who we are. It determines everything about us, including ones intellectual capabilities.
If one looks at, say in Britain our Council Estates with predominantly white people living there. What one finds is a very very high percentage of households where the males and often the females have a criminal record and the children are already known to the police.
The children, the teenage ones, also have a very very low rate of any sort of higher education, principally because their record has been incredibly poor at school.
Take that back and one finds their parents also had a poor school record. So it’s passed down through the DNA.
Take it further back and one would find the grandparents either in a manual labouring job or no job, again because of poor school record.
With record then to American black communities. Why can’t they get themselves out of this Ghetto-type situation? They don’t have the gumption that’s why.
They want people like you and me to do it for them, to help them, because they haven’t the gumption to help themselves.
America has the ultimate system to do this for them, Affirmative Action.
Affirmative Action proves they are totally unable to help themselves. That simply because they’re black they get a hand-up, NOT on MERIT like non-blacks, but because they’re black in itself.
Now that’s racist.
I am against affirmative action and agree that it meets the true definition of racism because it is based on color.
However, eugenics, which you clearly believe in, is the same coin as affirmative action. It also argues for the erasure of people based on traits that can include skin color. That can certainly be viewed as racism even though most true eugenicists approach the problem from a flawed logic tree.
Humans share about 90% of our DNA with primates so simply change my seed analogy to a a set of primate twins. Raise one with little stimulation and no nurturing and compare it’s twin that is raised in a nurturing environment with lots of stimulation. I would argue that you would get the same result as my prior analogy of plant seeds. The truth of planted seeds is scientifically sound and certainly applicable to people.
The environment/genetics argument is an age old argument and I believe science has shown and demonstrated that environment can overcome the statistical game of genetics. We are proving it just as our friends and family are proving it with their adopted children. Genetics certainly influence who we are, but they don’t define who we become.
Take a young child out of a statistically doomed situation and place them in a far better situation and he/she will usually defy their genetic history. This is simple science and even those who believe genetics is far more important than environmental influences are forced to admit the proof.
Genetics does not guarantee anything nor does environment, and at some point self-determination takes over. I have seen this personally over and over. We adopted, my sister adopted two from overseas, our best friends adopted two from Ethiopia, we were a foster family and lots of our friends are. A few years ago a young lady adopted as a baby from the Eastern Bloc was valedictorian at a private school here in my community - mostly very affluent students. What I personally see is not possible based on your perspective and that is not even arguing based on my faith and belief in a creator.
Make a different environment for those children, just like the primates in the analogy, and the supremacy of genetics is destroyed. This is true no matter where you are. The problem is changing the culture that forms the environment that shapes their future far beyond their ethnicity. On a macro-level look at the two Germany’s during the cold war and that was only a couple of generations - same genes far different result.
Genetics certainly has an influence, but I believe (scientifically) that environment is far more important than genetics.
