1. What is a pedigree?

A pedigree is a genealogical graph or table which records the relationship of families by degrees. Drawing a pedigree is always an essential step in genetic counseling. In medical records, a pedigree is also useful to document the family history of the patient. Drawing a pedigree is also necessary in collecting genetic resources for medical research such as positional cloning.

2. What is PediDrawTM?

PediDrawTM is an online pedigree drawing tool which enables you to generate your pedigree after you input your family information step-by-step. It is easy-learning and user-friendly without using any drawing software.
