THE ELEMENTARY COURSE IN 

 GENETICSi 



The elementary courses in botany and in 

 zoology have recently been the sixbject of con- 

 siderable discussion. One might think that 

 subjects as old and as well established as these 

 which have been taught for many years should 

 long ago have become definitely organized upon 

 the proper pedagogical basis. But these sub- 

 jects with their various subdivisions have 

 grown so large that it is becoming increasingly 

 difficult to give adequate treatment even in an 

 elementary manner to all phases of either of 

 these two primary biological sciences in the 

 time that js ordinarily available for the begin- 

 ning course. Teachers of these subjects are, 

 therefore, confronted with the choice of making 

 the beginning course an elementary survey of 

 the entire field of their subject or of bodily 

 eliminating certain phases, leaving their con- 

 sideration to later and more specialized courses. 



Genetics may properly be regarded as one of 

 these subdivisions or phases of biology — a 

 phase of applied biology if you will. But it 

 can not properly be regarded as a phase either 

 of botany or zoology alone, nor can it be ade- 

 quately treated in a course of instruction by 

 confining one's attention exclusively to one or 

 the other kingdom. The genetics instructor 

 must be free to select his illustrative material 

 from any source, plant or animal, economic or 

 non-economic, as he sees fit. While the greater 

 number of forms of animal life of economic 

 importance are to be found among mammals, 

 birds and fishes, and of plants among the
