The mating would therefore be represented: 
c? CBfl . CBfl X

$ 9 CcBbFfli, white 
d 71 cf CcB 2 f 2 Ii, white. 
In obtaining F 2 , the Fi cross-bred male possessing the formula 
CcB 2 f 2 Ii would form gametes of four sorts as follows: 
CBfl . CBfi . cBfi . cBfi 
while the female cross-bred, possessing the formula CcBbFfli would 
form gametes of eight sorts: 
CBfl . CBfi . cBfi . cBfi 
CbFI . CbFi . cbFI . cbFi 
The mating would therefore be represented
