Verified step by step guidance1
Understand that a pedigree is a diagram that shows the occurrence and appearance of phenotypes of a particular gene or organism and its ancestors from one generation to the next.
Recognize that genetic counselors use pedigrees to trace the inheritance of genetic traits or diseases through multiple generations within a family.
Analyze the pedigree to identify patterns of inheritance, such as autosomal dominant, autosomal recessive, X-linked dominant, or X-linked recessive traits.
Use the identified inheritance pattern to assess the risk of family members inheriting or passing on the genetic disease.
Communicate these risks and inheritance patterns to clients to help them understand how the disease may affect current and future generations.
