PREPOTENCY

indicate the direction, without showing the limits, of prepotency. 

 The following list from Pearson 1 includes the most accessible 

 data co-vering this point. Unfortunately again, much of the 

 material is drawn from studies in man, but fortunately also 

 horses and dogs have been included to some extent. It is all 

 useful in showing the mixed nature of prepotency. 



TABLE ILLUSTRATING PREPOTENCY OF SEX 



Here, in small compass, are results of studies sufficiently 

 extensive to justify careful consideration. The following con- 

 clusions are certainly warranted : 



i . The English father is prepotent over the mother in respect 

 to stature in both sexes (see lines i, 2, 3, 4) ; but the reverse is 

 true as to coat color in thoroughbred horses and in Basset 

 hounds, especially in the latter (see lines 7, 8, 9, 10). The con- 

 clusion of all this is that sometimes one sex is prepotent and 

 sometimes the other, and, accordingly, that each character must 

 be worked out by itself and for each race separately.
