TABLE 4 

 Summary of Results for Second Generation Hybrids, F 2 (Narrow X Wild) 



4, that the modal grade for all of the averages under savage- 

 ness is o ; under wildness or timidity, i or 2 . 



The results of tables 5 and 6 stand in striking contrast with 

 those of tables 3 and 4. Although the numbers of individuals 

 resulting from wide by wild crosses are small for both the first 

 and the second generation hybrids, the differences which appear 

 from comparison of tables 3 and 4 with 5 and 6 indicate clearly 

 the influence of the wild blood in the wide tame parent. 



We note from table 5 that fifteen F 1 individuals yield aver- 

 age grades which are about as high as those for the F t narrow 

 by wild. There is slight difference, however, in the case of the 

 F x wide by wild individuals for the sexes. The modal grade 

 for savageness, wildness, and timidity is seldom below 4 for 

 either males or females. In two cases it is 3. 



The second generation of wide by wild individuals grades 

 nearly as high as the first generation and is thus in marked 

 contrast with the second generation of the narrow by wild
