Pedigree Analysis is a method used in animal breeding to study and track family histories of animals. Think of it like a family tree investigation, but for animals. Breeders and livestock professionals use this to make smart breeding decisions by looking at the qualities of an animal's parents, grandparents, and other relatives. It helps predict what traits offspring might inherit and helps improve desirable characteristics in future generations, such as milk production in dairy cows or wool quality in sheep. This is sometimes also called "ancestry evaluation" or "lineage assessment."
