In AI, and higher ancestral generations, f = 

 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 AS, and higher ancestral generations, ff = 

 87.50 per cent of the dam's ancestors are animals 

 which are also ancestors of the sire. 



In A 7, 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^f = 

 92.97 per cent of the dam's ancestors are animals 

 which are also ancestors of the sire. 



In A 9 , and higher ancestral generations, f = 

 93.75 per cent of the dam's ancestors are animals 

 which are also ancestors of the sire. 



In Aio, and higher ancestral generations, 93.75 

 per cent of the dam's ancestors are animals which 

 are also ancestors of the sire. 



In A 11, and higher ancestral generations, 93.75 

 per cent of the dam's ancestors are animals which 

 are also ancestors of the sire. 



In A 12, and higher ancestral generations, 93.75 

 per cent of the dam's ancestors are animals which 

 are also ancestors of the sire. 



These percentages are quantities of a good deal 

 of interest. They measure the degree in which 

 King Melia Rioter 14th's sire and dam were
