Animal Breed Genetic Calculations and up breeding



Animal up breeding Calculations

Animal up breeding has been proven, through Scientific Research the World over in Animal Husbandry Breeding practices. Select up breeding programs have been utilized, to establish and create new breeds of animals, and or, to preserve rare and endangered Breeds of animals.
This is an example showing individual animal specimens resulting from up breeding programs, that possess less than 5% out cross genetics, and are scientifically considered Purebred. The small amount of 5% or less, outside influence of genetics, becomes no longer significant. 
​
Comparatively, F5 and F6 matings, and the matings of offspring produced from F5 and F6 matings, have already established the foundation of desired inheritable traits for the gene pool. Worthy F5 and F6 Stock can then be a consideration, to mate with the already established 100% Purebred Stock, resulting in all Offspring recognized as Purebred.

​***Formula: ___% mated with ___% (add percentage of each) = ___ + ___% = ___ (divided by 2, because both parents contribute) = ___% of resulting offspring.


F1~100% mated with a 0% (outcross animal) = 100 divided by 2 = 50 %


F2~100% mated with 50% = 150 divided by 2 = 75 %


F3~100% mated with 75% = 175 divided by 2 = 87.5 % (rounded up) = 88%


F4~100% mated with 88% = 188 divided by 2 = 94 %


***F5~100% mated with 94% = 194 % divided by 2 = 97 %
(and has less than 5% outcross or outside genetic influence)

* By utilizing Selective breeding of worthy specimens, 
that possess preferred attributes through out the up breeding process of  F1 through F5, and F1 through F6 matings, the desired characteristics and attributes are, and should be producing uniformity, with a high % of consistency in the F5 and F6 Offspring.


             F5 with F5 *97% mated with 97% = 194 divided by 2 = 97%

            F5 with F4 *97% mated with 94% = 191 divided by 2 = 95.5 % (rounded up) = 96%


F6~100% mated with 97% = 197 divided by 2 = 98.5% (rounded up) = 99%


           F6 with F6 *99% mated with 99% = 198 divided by 2 = divided by 2 = 99%

           F6 with F5 *99% mated with 97% = 196 divided by 2 = 98%

           F6 with F4 * 99% mated with 94% = 193 divided by 2 = 96.5% (rounded up) = 97%


F7~100% mated with 99% = 199 divided by 2 = 99.5% (rounded up) = 100 %


          F7 with F7 *100% mated with 100% = 200 divided by 2 = 100%

          F7 with F6 *100% mated with 99% = 199 divided by 2 = 99.5% (rounded up) = 100%

          F7 with F5 *100% mated with 97% = 197 divided by 2 = 98.5 (rounded up) = 99%

          F7 with F4 *100% mated with 94% = 194 divided by 2 = 97 %
