Basis of Eugenics
The science of eugenics roots largely on the fact that the human being is an animal subject to the same laws and principles that govern the rest of the animal kingdom. It has been observed that the basic genetic mechanism of man, mice, higher plants and molds appear to be the same and in principle the geneties of man is not unlike the genetics of a virus. For a long time man was considered a peculiarly awkward object of genetic investigation because his long life cycle and comparatively small individual progenies are indeed unfavorable to the use of certain standard research techniques of the geneticists. Moreover, we arc neither able to subject ourselves to rigorous experimental conditions nor do we desire to do so. In the standard genetic approach, closely controlled matings and standardized environment are prerequisite. Where man is concerned, these experimental ideas arc not feasible. Taking into consideration of above mentioned difficulties, the geneticists have evolved the technique of studying the family known as pedigree analysis.
