The selection of animals based on the performance of their ancestors is called pedigree selection. Pedigree selection involves examining the ancestry or genealogy of animals to identify those with desirable traits, such as high productivity, disease resistance, or other desired characteristics. In pedigree selection, animals with superior genetic backgrounds or ancestors are chosen for breeding to produce offspring with better genetic potential. This is because desirable traits are often inherited from previous generations, and thus animals with a strong pedigree are more likely to pass on these traits to their offspring. Overall, pedigree selection is an important breeding strategy used to improve the quality of livestock and ensure that desirable traits are passed down to future generations.
