crete case. Assume that 2 s = 32, or s 16. Start 

 with a single A A + 2 Aa + aa family. 

 Then 



O n -l = 0, 



p n -i = 0, 



tfn-1 = 0, 



r n -i = 1. 



Then in the next generation we shall have 



16 {0 + J (0) + T V (1)! =1 AA family 



+ 16 (HO) + J (1)} = 4 AA + Aa families 



+ 16 {J (1)| = 2 Aa families 



+ 16 \% (0) + + i (1)} =4>(AA+2Aa + ad) 



families 



+ 4 (Aa + aa) families 

 + 1 aa family. 

 This is the fact. 



In the next generation we shall have 



16 fl + 1 + iV (4)} = 36 AA families 

 + 16 U (4) + 1 (4)i = 48 (AA + Aa) families 

 + 16 f| (4)J = 8 Aa families 

 + 16 1| (4) + 2 + i (4,} = 80 (AA + 2 Aa + aa) 



families 



+ 48 (Aa + aa) families 

 + 36 (aa) families. 

 This is the fact. 



In the next generation we shall have 

 16 |36 + \ (48) + T V (80)| = 16 X 53 = 848 AA 

 families
