Please explain me pedigree analysis
Answers
Pedigree analysis describes the process of interpretation of information displayed as a family tree. The family tree or pedigree is constructed using a standardized set of symbols and will include information about the disease status of each individual. If only a single individual is affected within the family then the pedigree cannot in itself provide proof for a particular mode of inheritance and cannot distinguish inherited from noninherited conditions. When more than one individual is affected then the pattern may provide important clues or even proof of the mode of inheritance. There are four main patterns of inheritance that may be seen in a pedigree.
