PATHOLOGY

Detailed explanation-1: -A pedigree shows relationships between family members and indicates which individuals have certain genetic pathogenic variants, traits, and diseases within a family as well as vital status. A pedigree can be used to determine disease inheritance patterns within a family.

Detailed explanation-2: -By analyzing a pedigree, we can determine genotypes, identify phenotypes, and predict how a trait will be passed on in the future. The information from a pedigree makes it possible to determine how certain alleles are inherited: whether they are dominant, recessive, autosomal, or sex-linked.

Detailed explanation-3: -It can be used for a characteristic like having a widow’s peak or attached earlobes, or a genetic disorder like colorblindness or Huntington’s disease. Besides being used to represent familial characteristics in humans, pedigrees are also important in animals that are selectively bred for certain characteristics.

Detailed explanation-4: -It can be simply called as a “family tree". Pedigrees use a standardized set of symbols, squares represent males and circles represent females.
