A study of table 31 shows clearly that as the amount of black 

 decreases in the parents it diminishes in the offspring. Thus in black 

 X black matings the commonest grade of the children is black; in 

 black X dark brown or medium brown, and in dark brown X dark 

 brown matings the commonest grade in the children is dark brown; 

 but in the dark brown X medium brown or light brown matings it is 

 medium brown. The cases are not numerous where the children are 

 darker than the darker parent, and very light children ("flaxen")
