In A if and higher ancestral generations, § = 

 62.50 per cent of the dam's ancestors are animals 

 which are also ancestors of the sire. 



In A 5 , and higher ancestral generations, yf = 

 75.00 per cent of the dam's ancestors are animals 

 which are also ancestors of the sire. 



In A 6, and higher ancestral generations, f| = 

 87.50 per cent of the dam's ancestors are animals 

 which are also ancestors of the sire. 



In At, and higher ancestral generations, ff = 

 92.19 per cent of the dam's ancestors are animals 

 which are also ancestors of the sire. 



In A 8 , and higher ancestral generations, y|| =

These percentages are quantities of a good deal 

 of interest. They measure the degree in which
