HEREDITY OF WILDNESS AND SAVAGENESS IN MICE 



57 



In Mating IV ( 9 W-S X d" T-N) in which case the male 

 parent is tame and non-savage the percentages for wildness 

 and tameness are identical, while those for savageness and non- 

 savageness are 0.432 and 0.566 respectively. This seems to 

 indicate that the hereditary influence of the parents was about 

 equally divided between wildness and tameness and between 

 savageness and non-savageness.

of F3 Hybrids, Series B 



In Mating VI ( 9 W-N X cf W-N) the wildness percentage 

 is 0.665 and the non-savage 0.575 in comparison with 0.333 for 

 tameness and 0.432 for savageness. The effect of the grading 

 in the parents seems to be here also quite apparent. 



The percentage for non-savageness in Mating VII ( 9 W-N 

 X cf T-N) is 0.651 in comparison with 0.347 for savageness. 

 While this seems to show the effect of the non-savageness of 

 the parents, there was no equalization of wildness and tameness 

 as the percentages for these are 0.607 and 0.391 respectively.
