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

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

 Then 



O n -l = 0, 

 Pn-1 = 0, 

 tfn-1 = 0, 



r..i = 1. 



Then in the next generation we shall have 

 16 {0 + i (0) + T V (1)} =1 AA family 



+ 16 }J (0) + \ (1)} = 4 ^^ + ^a families 



+ 16 fj (1)} = 2 ^a families 



+ 16 {J (0) + + J (i)} =4<(AA+2Aa + ad) 



families 



+ 4 (^4a + ad) families 

 + 1 aa family. 

 This is the fact. 



In the next generation we shall have 



16 {1 + 1 + iV (4)1 = 36 AA families 

 + 16 fi (4) + i (4)S = 48 (AA + Aa) families 

 + 16 f J (4)1 = 8 ^4a families 

 + 16 f }(4) + ^ + i (4,J = 80 (AA + 2 Aa + aa) 



families 



+ 48 (^4 a + aa) families 

 + 36 (aa) families. 

 This is the fact. 



In the next generation we shall have 

 16 J36 + 1 (48) + T V (80) j = 16 X 53 = 848 AA
