The pedigree for 12 ancestral generations of the Jersey bull 

 King Meha Rioter 14th (103901) may be taken as the first 

 illustration.

Table 5 is clearly the one which demands special attention. 

 As will shortly appear, it is the most important for the theory 

 of inbreeding. Let us attempt its analysis. Just what does the 

 first entry mean genetically? It states that King Melia Rioter, 

 an animal which first appeared on the sire's side of the pedigree, 

 reappeared in the second ancestral generation on the dam's

Fig. 51. Diagram showing (o) the total inbreeding (heavy sohd line) 

 and (6) the relationship (heavy broken line) curves for the Jersey bull, 

 King Melia Rioter 14th. The high order of the inbreeding and relation- 

 ship between the sire and dam in this case is evident by comparison with 

 the lighter lines, which give the maximum values for continued brother 

 X sister, and parent X offspring.
