Questions to answer:

1. Why are pedigrees useful for tracking the inheritance of diseases and other traits?

2. Explain the mode of inheritance (autosomal dominant, autosomal recessive, sex-linked, sex-limited), the cause, and the symptoms of each of the following genetic conditions:

   1. Cystic Fibrosis

   2. Tay-Sachs Disease

   3. Sickle Cell Anemia

   4. Huntington’s Chorea

   5. Hemophilia

   6. Male Pattern Baldness (NOT A DISEASE- Thank you very much!)

3. Why is inbreeding a bad idea?

Things you should make sure you understand:
