Pedigrees show how characteristics are passed from one generation to the next. They are used in studying human genetics because it is not possible to carry out controlleâ¦d breeding experiments with humans, as we can with other animals or with plants.
Reading Pedigrees. The horse you see--or the foal you envision--reflects generations of ancestors. Owners of those ancestors made decisions on mating horses, planning each generation. They selected animals by examining the successes of previous horsemen, as recorded in pedigrees. Each breed includes individuals which meet a standard of a breed registry.
