Pedigree Analysis of Bulls in Section 2 - December 2018
gradient line
The following table lists the bulls which have the highest average percentage of genes in common with the bulls in Section 2A. This value can be used as an indicator of which sires are having a large contribution to the Holstein breed. The percent of genes two related bulls have in common depends on how many generations separate them. For example, on the average 50% of a bull's genes are identical to the genes of his sire, 25% to one of his grandsires and 12.5% to one of his great grandsires.

Percent Genes in Common is calculated as the total of:
GENES IN COMMON = 1.0 (if the bull appears in Section 2)
 

+ 0.5 times the number of sons
+ 0.25 times the number of grandsons
+ 0.125 times the number of great-grandsons
+ 0.0625 times the number of great-great-grandsons.

 
 

This total is then divided by 513. (Total bulls in Section 2).

Total percent genes in common of all bulls combined is more than 100% because several of the bulls listed above are related to each other. For example, half of the genes which O-Bee Manfred Justice-ET has in common with the Section 2 bulls are also the same genes which his sire, Ha-Ho Cubby Manfred-ET, has in common with these bulls.
