The total inbreeding and the relationship curves are given in 



Fig. 52- 



The difference in the breeding of this bull and the one con- 

 sidered in the former example is striking. In the 8th ancestral 

 generation Blossom's Glorene has but 60 per cent, of the num-

Fig. 52. Diagram showing the total inbreeding (heavy solid line) 

 and the relationship (heavy broken line) curves for the Jersey bull 

 Blossom's Glorene, over a period of eight ancestral generations. Com- 

 pare with Fig. 51. 



ber of different ancestors possible in that generation, but not 

 one single animal in the ancestry of his sire occurs in the ances- 

 try of his dam (within the limits Ai to As). The probability is 

 that Blossom's Glorene is heterozygous in respect of many of 

 his characters, while King Melia Rioter 14th is homozygous. 



The pedigree of Blossom's Glorene is shown in Pedigree Table
