 the Fsb where they are, respectively, 0.469 and 0.224. 



In table 39 appear the results of the Fi hybrids divided ac- 

 cording to the matings of the parental stock, i.e., wild female 

 and tame male, or tame female and wild male. With the ex- 

 ception of the results from the matings of tame female with wild 

 male in Series A, the percentages follow the order noted in the

Fl generation in table 38, namely, wild-savage , wild-non-sav- 

 age, tame-non-savage, tame-savage. In the case of this ex-

 males. In the combined results of the males and females the 

 wild-non-savage mice are in greater numbers, the wild-savage
