Characteristics of Pedigrees

Statements like the following, make it desirable for the student 

 to have an accurate acquaintance with the foundation animals in 

 any breed. 



Of all the nearly eight thousand animals imported the real founda- 

 tion of the aristocracy rests upon about three dozen animals. It is im- 

 possible to measure exactly the contributions of the other 99 per cent of im- 

 ported animals, but the preponderance of this small group in the pedigrees 



of our leading producers in both short-time and long-time tests and of our 

 leading show ring winners as well, leads straight to the conclusion that it is 

 prepotency of these blood lines that has been responsible for the supremacy 

 of the breed. 



Each student may take the names of each ancestor in the pedi- 

 grees he has just made, one ancestor for each slip. The cards found 

 between manual pages 67-68 form an easy method of handling these 

 data. A sample of the way one of these cards is made out is shown 

 for Sir Johanna Butter Boy sire of Korndyke Butter Girl Johanna 2d.

The red slips are for the Advanced Registry bulls, green for the 

 Advanced Registry cows, blue for the random sample bulls, and white 

 for the random sample cows. In this way the different sets of 

 pedigree data will not be mixed. When each student has arranged 

 this data on the slips, have the slips of the whole class combined into 

 four groups (Advanced Registry bulls, Advanced Registry cows,
