Common items that show on a pedigree chart are name, date of birth, sex, genetic information and ancestors. People use pedigree templates for humans and animal husbandry. The charts typically include four or five generations of ancestors.
Other items include place of birth, place of death and date of death. A human chart proves useful for tracing a family tree and tracking genetic diseases, whereas an animal husbandry chart helps in planning a selective breeding program to promote desirable traits. Either may be vertical or horizontal and begins with an original set of parents. Over time, people add new generations to the chart.
