THE ABSENCE OF DOMINANCE 69 



tion than 3:1, Mr. Wentworth bases his suggestion 

 on the fact that certain hybrid roans {i.e. the progeny 

 of whites and reds) threw 64 calves, of which 36 were 

 roans, 11 reds, and 17 whites. These figures are cer- 

 tainly very close to the 9:3:4 ratio, but they are not 

 far from the figures demanded by the other theory, 

 namely, 32 roans, 16 reds, and 16 whites.
