CHARLES A. COBURN 



throughout the Series of Mating I but is noted only in the 

 inheritance of wildness and tameness in Mating II, the propor- 

 tion of savage and non-savage varying greatly in each case. 



On the following pages there are presented three repre- 

 sentative genealogical charts which give the number of lit- 

 ters from each mating, the classification of the mice and 

 the numbers of the individual breeders.

A closer study of these charts reveals instances of inheritance 

 which suggest the possibility of some slight segregation of the 

 behavior-complexes under consideration. An example of this 

 may be found in charts 1 and 2, graphically illustrated as follows:
