How to Calculate Bloodline Percentage
• for one ancestor • a tutorial using your registered animal's pedigree •

    Let's say you own an excellent cow named Ye Grand Olde Effigy. She is valuable to you because of her "Effin" bloodline, named after a famous 1964 bull in her pedgree, "Sir Effin Riddick Ullyses". You want to calculate exactly what percentage "Effin" bloodline this old girl carries. (You may need an extended pedigree to figure that for very old bloodlines).
     Each generation in the pedigree (parents, grandparents, great grandparents, etc.) is one column. The 1st generation is an animal's parents, the 2nd generation is the animal's grandparents, and so on. To calculate a bloodline percentage, all instances of that ancestor in your animal's pedigree must be located and counted.

    For calculating the percent of Effin in Effigy's pedigree, you must trace the pedigree to include all animals born as far back as 1964 to include every generation that Effin could appear in Effigy's pedigree.

  1.   1st generation = 50% each
  2.   2nd generation = 25% each
  3.   3rd generation = 12.5% each
  4.   4th generation = 6.25% each
  5.   5th generation = 3.125% each
  6.   6th generation = 1.5625% each
  7.   7th generation = .78125% each
  8.   8th generation = .390625% each
  9.   9th generation = .1953125% each
  10. 10th generation = .09765625% each        

    Next, you must count up the number of times Effin appears in each column of the pedigree.
    Each column of ancestors in the pedigree represents a certain percent. You can see the pattern is half the value of the previous generation:

1st generation
2nd generation
3rd gen
4th gen
5th gen
2 parents
4 grandparents

16 gg-gps
32 ggg-gps

8th gen
9th gen
10th gen

128 ...
256 ...
512 ...
1024 etc
1.5625%
.78125
.390625
.1953125
.09765625
.015625
.0078125
.00390625
 .001953125
.0009765625

    Count each time "Effin" appears in Effigy's pedigree, in every generation's column, and sub-total the numbers below each column. Then, add up all the column subtotals to calculate Effigy's actual (Effin) bloodline percentage. That's it.

    There is no single definition, but Effigy could generally be considered "Effin bred" if she is > 10% Effin. If she were less than 10% Effin, Effigy would more likely be called "Effin influenced." However, different breeders, breeds, registries and associations will vary somewhat in semantics.

    More debatable is genetics in real life... When genetic probabilities, compared to actualities, refuse to remain centrally located on the bell curve. For example, one 31.25% Effin bred cow may have inherited copious amounts of Effin's finest genetic attributes that he is renowned for. Whereas another 31.25% Effin bred cow may not have inherited much, if any of his best genetics. That is where breeding becomes an art, beyond the science.

Qualities shared among the best breeders include:

  • They understand how genetics work in theory and in real life.
  • They understand the inheritance of both dominant & recessive genes.
  • They understand prepotency.
  • They understand genotype, phenotype, linebreeding, inbreeding.
  • They realize that straight flushes and fertile mules exist in the real world.
  • They search, find, acquire, breed and reproduce valuable, stacked genetics.

    It is worth mentioning here that an animal can have a pedigree that reflects a high percentage of 2 or more bloodlines, or, it may not contain a high percentage of any single bloodline. An animal can be a product of outcross bloodlines (NOT the same as crossbred, mind you), or linebreeding or inbreeding.
