Category : 12th Class

Eugenics

The term eugenics (Gr. Eugenes, well born) was coined by British scientist Sir Francis Galton in 1883. Galton is called ‘Father of eugenics’ as this branch has been started by him.

Eugenics is the branch of science which deals with improvement of human race genetically. Eugenics can be divided into two types :

(1) Positive eugenics : In this approach of eugenics the future generations are improved by encouraging the inheritance of better traits.

(2) Negative eugenics : This is a negative aspect of improving mankind by restricting the transmission of poor and defective germplasm.

Euthenics

Euthenics is the improvement of human race by improving the environmental conditions, i.e., by subjecting them to better nutrition, better unpolluted ecological conditions, better education and sufficient amount of medical facilities.

Euphenics

The study of born defectives and their treatment is called euphenics. The term euphenics was given by A.C. Pai (1974) for symptomatic treatment of human genetic disease especially in born errors of metabolism.
