Eugenicists used to divide eugenics into two types; positive and negative. To start with the positive type, it addresses the high-class people that have superior genes (intelligence, good health, good looks...) and encourages them to mate and reproduce yielding "good births". On the other hand, the negative type of eugenics discourages the mating of the low-class people that have inferior genes (diseases, disabilities...) to reduced the rates of "bad birth". This procedure assures "selective breeding" in the …show more content…
After the availability of an in-vitro fertilization option to women, they were given the choice to use these sperms to reproduce with men having superior and good quality genes, despite of getting involved in relationships.
Pre-implantation genetic diagnosis is one other technique that helps prospective parents. Upon choosing the in-vitro fertilization, parents can choose to test the cells they are using for preferable genes, or avoid fertilization in case of not preferred ones. In case of in vivo fertilization (the natural way), prenatal genetic tests had a positive impact on that. Prenatal genetic diagnostic tests used to take place during the second trimester traditionally, or during the first trimester recently. These screening tests help prospective parents to identify specific genes and genetic markers of their fetuses. This way, parents can choose to abort fetuses with undesired traits. Talking about the science of eugenics, and how is it really done, we get to define the term
