They help geneticists to find the probability of different things, like whether a child will be a boy or a girl. They can be used to isolate diseases. A pedigree is a written bloodline. It shows males and females, children and parents, and it also can show a specific genetic trait. Normally, in a pedigree a circle represents a female and a square represents a male. The black circles or squares can represent some sort of disease in the family, while a white circle or square can represent a healthy member of the family. In the family in the picture below, the disease seems to be recessive since only four members out of the whole family of sixteen (through four generations) have or had the disease. The black circles or squares could also represent someone who had brown eyes, while all the white circles and squares could represent someone with blue eyes. That would mean that blue eyes are dominant over brown eyes in this family.
A pedigree can be useful for breeders and scientists. In the breeder's case, the breeder can pick and choose which animals to breed according to their pedigree. A person would be more likely to buy an animal that came from a healthy, sound background than an animal that came from a background of unhealthy, unstable animals. In the scientist's case, a pedigree can help the scientist track a genetic trait throughout a family's generations. If the genetic trait is something harmful such as hemophilia, a scientist could isolate that trait in the family. Also, pedigrees can help geneticists find the probability of whether a baby will be a boy or a girl. A pedigree analysis takes into account the phenotypes of as many members of a family as possible. If a couple want to have a child but either one or both of their families have a history of a hereditary disease. Also, if a pedigree is properly diagrammed, it can provide helpful details about a family such as genetic characteristics and diseases. A pedigree can also provide family information of diseases or traits and history of the family.
