Genetics and Eugenics 
“Genetics is the science which seeks to account for the resem- 
blances and the differences which are exhibited among organisms re- 
lated by descent.” 
“Eugenics is the study of agencies under social control that may 
improve or impair the racial qualities of future generations, either 
physically or mentally.” 
“An exact determination of the laws of heredity will probably 
work more change in man’s outlook on the world, and in his power 
over nature, than any other advance in natural knowledge that can be 
clearly foreseen. 
“To gain this knowledge is the object of the science of genetics, 
which proceeds in practice, largely by means of plant breeding and 
animal breeding for the reason that heredity is less complicated in 
these organisms than in man, and its operation can be more easily 
made out. The knowledge so gained finds its application in methods 
for the improvement of cultivated plants and domesticated animals 
and, most important of all, in the improvement of the human race, 
through the science of eugenics.” 
In the world’s life of today it is a duty and a responsibility to be 
interested in the great questions of inheritance, and to possess a work- 
ing knowledge of the methods for the improvement of living things. 
Consider the importance of this in your own life, and in the lives of 
those about you. The Association welcomes into its membership all 
those who are influencing the thought and progress of the present, and 
the young people who are going to be the thinkers and leaders of the 
next generation.
