Negative Eugenics

Negative Eugenics
The negative eugenics attempts to eliminate the defective germplasm of the society by adopting following measures:
1.Sexual separation of the defective-The defective persons may have various sex-linked diseases such as night blindness, haemophilia colour blindness, etc., and various other defective traits which maybe regulated by dominant or recessive genes. The increase of germplasm of the persons having such defective traits in the population can be checked by keeping them away and separated from the society. Different states have wisely adopted the restricted measures in segregation of the mental defectives from the society and to place them in mental hospitals.

2. Sterilization-The sterilization is the best means to deprive an individual from his power of reproduction without interfering with any of his normal functions. The sterilization method is based on surgical operation of sperm duct or vas deferens in males and oviducts or fallopian tubes in females. The former is known as vasectomy and the later is splengectomy. The family planning movement in India has adopted the sterilization as the tool for controlling the rate of vastly increasing population and in that case the sterilization is euthenical in its application than the eugenical.
3. Control of immigration-Through immigration there are enough chances that undesirable or defective genes of different races and nationalities may intermingle with the normal germ plasm of the populations. Therefore, the immigration rules must be strict and the persons with undesirable hereditary traits must not be allowed to migrate from one place to another.

4.Regulation of marriage-Presently most human societies are money-minded and for the marriage relationship the wealthy or highly planed persons which. however, may contain several defective genetical traits, are more preferred than those which have eugenically sound hereditary traits but having no money and which fail to reach to highest status of the society due to lack of opportunities. Some rule must be enacted to encourage the marriages among desirable mates.
Recently human geneticists have devised following two eugenically sound methods (i.e., euphenics and genetic engineering) for the improvement of human race:
