Artificial insemination is used to produce offspring cows and other milch varieties like buffaloes.. etc often use same sturdy males. Isn't it a step towards eugenics? What can be possible future harms?

And what do you mean by "number dominance of Caucasians"? – Bryan Krause Sep 11 '19 at 00:24

"number dominance of Caucasians over other human divisions".... The phrasing is unclear but please note that there are ~1.3 billions Han Chinese and only ~0.85 billions caucasians. – Remi.b Sep 11 '19 at 04:06

Does it make sense to classify all humans in a single species? might also be a possible duplicate. – Remi.b Sep 11 '19 at 04:10

There is no genetic basis for these classifications. Most human genetic diversity is in Africa. Diversity only decreases with geographic distance from this continent. There are geographic clines, not the clusters that one might call race. Here are some results from Rosenberg's 2002 Genetic Structure of Human Populations:
- 93-95% of variation occurs within populations
- 3-5% of variation occurs between populations
Local adaptation occurs, such as height and pigmentation but these phenotypes are polygenic and should not lead to binary classifications. There are some very interesting case studies on local adaptation that you should look into. ex)EPAS1 gene and no hypoxia among Tibetans or lactose persistence on three continents
There is no genetic basis for dominance of one population over another.
