Summary Introduction
Introduction: A pedigree depicts the interrelationships between parents and offspring over generations for a particular trait. It is also referred to as a family tree. Individuals and relations are denoted by symbols and lines. It contributes in predicting the occurrence of that particular trait in future generations through inheritance patterns and genotyping the individuals.
