the principal of eugenics are racism and abortion..
Eugenics is defined as "the belief and practice which aims at improving the genetic quality of the human population." Determining the genetics of those who desire to become parents and then giving only those with desired genetics a license to become a parent would certainly be a form of eugenics. It would be difficult to enforce without having harsh, and what many would believe inhumane, penalties for those who have children without a license.
Francis Galton developed the theory of Eugenics
There are two types: positive and negative. Positive eugenics involves advantaging people who have superior genes. Negative eugenics involves sterilizing people who have inferior genes.

eugenics is a term referring to the science of improving the racial question of humanity through selective breeding of superior types.
