We’re being explained about chromosomes and gametes and shit, and the recent video we watched mention Chromosomes cross-exchange in the gametes in the first or second cycle. The idea I understood was “genes are swapped between them, so they won’t end up really anything like the parents” which confused me more because that is pretty much how genetics work. I am like my mother physically, and my dad in the metabolistic and internal systems. So I asked my science teacher if the cross-exchange was why eugenics is seen as illegitimate, and she said something along the lines of “no, eugenics is about making a pure race, but often there is more genetic variation intra-race than inter-race.”
​
I don’t understand this? Does she think race is a continental thing? Because a northern euro is far different than a south Euro in genetics, to the point I would call different races entirely. And there is far more difference between race in the phenotype viewpoint.
​
tl;dr learning about chromosomes, mitosis and meiosis, and sexual reproduction, and I am confused about the cross-exchange and what my science teacher is saying. What is the scientific flaw about eugenics? Not its practical flaw in which I could name many, what is it’s scientific flaw?

Eugenics has a bad reputation due to being imposed on people (forced sterilization …) in the past. Genetic counseling before having children and genetic testing of the unborn to make sure they are healthy is also a type of “eugenics” but today we do not call it eugenics due the bad reputation that term has. All of this is voluntary thus our perception about it is different.
