Detailed explanation-1: -(PEH-dih-gree) A diagram of family history that uses standardized symbols. 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.
Detailed explanation-2: -What is Pedigree Analysis? Pedigree analysis was developed to understand the inheritance of genes from parents to offspring. It was developed as a chart that can represent a family tree along with the family members and their genetic traits, respectively.
Detailed explanation-3: -… A pedigree, as related to genetics, is a chart that diagrams the inheritance of a trait or health condition through generations of a family. The pedigree particularly shows the relationships among family members and, when the information is available, indicates which individuals have a trait(s) of interest.
Detailed explanation-4: -A chart which displays the affected members of a family by genetic diseases in the form of a family tree is called pedigree chart. The study of such a chart to detect genetic diseases in a family is called pedigree analysis. The diagram gives some common symbols in pedigree analysis.
Detailed explanation-5: -Explanation: The pattern of inheritance of Mendelian disorders which are transmitted to offspring as per Mendelian principles, can be traced in a family by using the pedigree analysis which is a method of studying human genetic disorders.
