A record of inheritance of certain genetic traits for two or more generations presented in the form of a diagram or family tree is called pedigree. Analysis of traits in a several generation of a family is called as pedigree analysis. It is employed in case of human beings and domesticated animals.
Importance:
(i) In human genetics, pedigree study provides a strong tool which is utilised to trace the inheritance of a specific trait, abnormality or disease.
(ii) It is useful for the genetic counsellors to advice in tending couples about the possibility of having children with genetic defects like haemophilia, colour blindness, alkaptonuria, thalassemia and sickle all anaemic.
